With my upgrade to 10.8 OS X Mountain Lion, one of the downside I found as a Unix System Administrator is that Apple have decided not to package X11 into the operating system anymore. I require X11 to run X apps to my OS X desktop. After some google searching X11 is now a seperate package. You need to download the XQuartz package from here http://xquartz.macosforge.org/landing/ Once downloaded, just install and reboot your Mountain Lion machine and reboot.
