[OS X TeX] Upgrading to Mountain Lion

We have discovered a minor problem if you install MacTeX and then upgrade
to Mountain Lion. This problem will not occur if you install directly on Mountain

MacTeX installs two Ghostscript binaries in /usr/local/bin, gs-X11 with X11 support
and gs-noX11 without X11 support. It sets gs to be a symbolic link to the
appropriate binary depending on whether or not you installed X11.

Once you upgrade, you may receive a message that you need to install
Xquartz. That is because Apple now wants you to obtain Xquartz directly
from the developers, so the Mountain Lion upgrade removes X11.

There are two easy solutions:

     a) Download Xquartz


     b) Change the symbolic link by running Terminal in /Applications/Utilities
and typing

	cd /usr/local/bin
	sudo rm gs
	sudo ln -s /usr/local/bin/gs-noX11 gs
