Thanks for reporting this. People have written me privately as well.

The problem is simple. Apple used to supply X11 with it's system, but no longer does.
Instead, the open source authors now supply it directly, and therefore can provide
more timely updates.

There are two versions of the Ghostscript binaries, gs-X11 and gs-noX11. When
MacTeX installs Ghostscript, it creates a symbolic link from the appropriate binary
to gs in /usr/local/bin, depending on whether you have X11 or not.

But when you upgrade the system, Apple removes X11, expecting you to get the
latest version.

There are two possible fixes. Either

	a) Create a new symbolic link in /usr/local/bin, named gs and pointing to


	b) Install X11, obtaining it from
