So i needed some way to obtain the InstallESD.dmg, this would allow me to burn it to disc (if my Air had a DVD drive) create an installable USB stick for OSX or simply create an ISO so i can burn the install DVD on Windows.
It turns out you can extract a full OS X 10.8 Mountain Lion install disc from your Macbook Air / Pro quite easily. I found some old instructions on Macworld aimed at doing the same for OSX Lion on a Macbook Pro also worked for OSX Mountain Lion on my Macbook Air.
1. Open the Terminal, and type this command to list all partitions on your hard drive or SSD:
diskutil list
2. Look for ‘Recovery HD’ in the list, and note its identifier. It will be something of the form diskXsY, where X and Y are numeric digits, for me the identifier was disk0s3
3. Type the following command to mount the recovery HD:
diskutil mount readOnly /dev/[identifier]
4. Replace [identifier] above with the identifier you obtained from step 2. So on my machine, I typed:
diskutil mount readOnly /dev/disk0s3
Your identifier could be different
5. The disk image inside the recovery HD is invisible, so use the Terminal to mount that too:
hdiutil attach “/Volumes/Recovery HD/com.apple.recovery.boot/BaseSystem.dmg”
6. Now, from the newly mounted Mac OS X Base System image, double-click the ‘Install Mac OS X Mountain Lion’ application at the root of the disk.
7. Go through the license agreement. Once it asks you for a disk to install on, choose the external drive or spare partition. For this i used a 16gb USB memory stick.
8. Enter your admin password when prompted, and the installer will start downloading.
When the download has finished the installer will re boot your Mac, so we need to stop it from doing this.
MacWorld had the following tip:
Open an old-style (non-autosaving) application that still uses the traditional Save, Save As…, etc. commands in the File menu (I used TextWrangler) and make a new unsaved document, and type a few things in it. This will give you a little insurance against the installer rebooting the system, since the app won’t let the system reboot until you respond to its message asking whether you want to save the document or not.
I just kept an eye on it and force closed it before the timer counted to 0.
9. Once the file finishes downloading, the installer will extract the InstallESD.dmg image from it and delete the package. This will be fine as long as you don’t let the app restart your machine. Once the installer finishes download and prompts you to restart your Mac, force-quit it. Do this quickly, as it may automatically reboot for you after a 30 timeout period (although if you’ve got an unsaved document open, you should be able to prevent that).
10. Os x yosemite to el capitan. If we look at the USB drive we told OSX to save the data to you should see an OS X Install Data folder
11. Open the OS X Install Data folder and you will find an InstallESD.dmg
12. This is your full OS X 10.8 Mountain Lion install disc, you can burn it to a DVD, image it to a USB flash drive to create a USB installation disc or use dmg2iso to convert the DMG to an ISO which can be burned by a popular image burning application, such as ImgBurn on Windows. The ISO can be used on Esxi, VmWare and so on if you decide to convert the DMG to an ISO.
13. The end result is your choice of installation media for OS X 10.8 Mountain Lion, I wanted to obtain an ISO so i could install OS X 10.8 Mountain Lion on my VmWare Esxi Server. As you can see OSX 10.8.3 was downloaded, as 10.8.4 was only released a few days ago i imagine eventually you should be able to get an up to date install dmg by doing this.

Checksums for our packaged downloads are contained in the corresponding checksums file.
The public key to verify the detached GPG signatures can be found under the attachments section on jmr's wiki page. (Direct Link).
Please note that in order to install and run MacPorts on macOS, your system must have installations of the following components:
Apple's Command Line Developer Tools can be installed on recent OS versions by running this command in the Terminal:
Older versions are found at the Apple Developer site, or they can be installed from within Xcode back to version 4. Users of Xcode 3 or earlier can install them by ensuring that the appropriate option(s) are selected at the time of Xcode's install ('UNIX Development', 'System Tools', 'Command Line Tools', or 'Command Line Support').
The easiest way to install MacPorts on a Mac is by downloading the pkg or dmg for Big Sur, Catalina, Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Lion, Snow Leopard, Leopard or Tiger and running the system's Installer by double-clicking on the pkg contained therein, following the on-screen instructions until completion.
This procedure will place a fully-functional and default MacPorts installation on your host system, ready for usage. If needed your shell configuration files will be adapted by the installer to include the necessary settings to run MacPorts and the programs it installs, but you may need to open a new shell for these changes to take effect.
The MacPorts “selfupdate” command will also be run for you by the installer to ensure you have our latest available release and the latest revisions to the “Portfiles” that contain the instructions employed in the building and installation of ports. After installation is done, it is recommended that you run this step manually on a regular basis to to keep your MacPorts system always current:
At this point you should be ready to enjoy MacPorts!
Type “man port” at the command line prompt and/or browse over to our Guide to find out more information about using MacPorts. Help is also available.
If on the other hand you decide to install MacPorts from source, there are still a couple of things you will need to do after downloading the tarball before you can start installing ports, namely compiling and installing MacPorts itself:
These steps need to be perfomed from an administrator account, for which “sudo” will ask the password upon installation. This procedure will install a pristine MacPorts system and, if the optional steps are taken, remove the as of now unnecessary MacPorts-2.6.4 source directory and corresponding tarball.
To customize your installation you should read the output of “./configure --help | more” and pass the appropriate options for the settings you wish to tweak to the configuration script in the steps detailed above.
You will need to manually adapt your shell's environment to work with MacPorts and your chosen installation prefix (the value passed to configure's --prefix flag, defaulting to /opt/local):
Lastly, you need to synchronize your installation with the MacPorts rsync server:

Upon completion MacPorts will be ready to install ports!
It is recommended to run the above command on a regular basis to keep your installation current. Type “man port” at the command line prompt and/or browse over to our Guide to find out more information about using MacPorts. Help is also available.
If you are developer or a user with a taste for the bleeding edge and wish for the latest changes and feature additions, you may acquire the MacPorts sources through git. See the Guide section on installing from git.
Purpose-specific branches are also available at the https://github.com/macports/macports-base/branches url.
Alternatively, if you'd simply like to view the git repository without checking it out, you can do so via the GitHub web interface.
If you already have MacPorts installed and have no restrictions to use the rsync networking protocol (tcp port 873 by default), the easiest way to upgrade to our latest available release, 2.6.4, is by using the selfupdate target of the port(1) command. This will both update your ports tree (by performing a sync operation) and rebuild your current installation if it's outdated, preserving your customizations, if any.
Running on platforms other than macOS is not the main focus of The MacPorts Project, so remaining cross-platform is not an actively-pursued development goal. Nevertheless, it is not an actively-discouraged goal either and as a result some experimental support does exist for other POSIX-compliant platforms such as *BSD and GNU/Linux.

Normally you must install from source or from an git checkout to run MacPorts on any of these platforms.
