[OS X TeX] Yosemite install broke LaTeXiT (and Ghostscript)

[Ettore Aldrovandi]

The strange thing is that /usr/local/bin/gs was pointing to gs-noX11 before, and to gs-X11 after, if I understand correctly.  Whatever the installer does, /usr/local is usually left alone.

BTW, /Applications/Utilities/X11.app is a stub and XQuartz lives in /opt/.
