X11 for Mac OS X is an implementation of the X Window System that makes it possible to run X11-based applications in Mac OS X, for eg. Open Office or GIMP. If you are not using any of such applications in your Mac then it’s better to uninstall X11 from your Leopard installation so as to save up on the disk space. If ever you feel like installing it again then you can use your Leopard DVD to do so.
But the standard (move to trash) uninstall won’t work here, so we have to uninstall it completely using the terminal in OS X.
Write or copy & paste the following command in your terminal:
sudo rm -rf /Applications/Utilities/X11.app /private/etc/X11 /usr/X11R6 /usr/bin/open-x11 /usr/lib/X11 /Library/Receipts/X11User.pkg
That is one single line. Be very careful as a small typo can cause problems and you may have to reinstall OS X. Therefore do this at your own risk.

Thanks!
Nice work dude! Keep going!
Don’t do it! It’ll make it so that you can’t reinstall it from the web. I’m not sure what the best method is for COMPLETELY removing X11, but this method now keeps me from re-installing X11 from the Apple website, because the installer thinks the other version is still installed.
Adam, did you manage to solve the complete unistalation of X11 so to be able to install it again from apple avoiding the ‘newer version already installed” problem?
Thanks,
Alejandro
Where is this ‘terminal’?
I don’t know what you mean or where to find it :S
Please can you email me back asap? Need to remove Gimp!
thanks
I did but didn’t helped me… still the same even after system reboot…
mf x11…
I got exactly the same problem, still cannot reinstall it cause it says a newer version is already installed, I go to load an application up that needs x11 and it says its not installed…
I too have run into this “newer version” problem. Am I to guess that there’s some sort of log that the installer is looking at? If so, how does one go about fixing this? Please give step by step instructions. Thanks!
It’s checking against your version of OSX. Higher than 10.4 and it says there’s a newer version. No quick fix that I can figure out… I’d just reinstall OSX if it bothered me that much.
