(well, the title was too good to pass up.)

I am having problems with FindX11 on Mac OS 10.7 (Lion). FindX11 unpredictably finds libraries in /usr/X11R6/lib and symbolic links to libraries in /opt/local/lib (the MacPorts port library.) On Lion, the Apple X server files always reside in /usr/X11; include files in /usr/X11/include and libraries in /usr/X11/lib. All other locations are symbolic links, except in the unusual case when a Lion system has a non-Apple X server.

Is there any simple way to tell FindX11 to leave /opt/local (and probably also /sw and /usr/local) alone, unless I want it to pay attention to them? Or perhaps only use the Apple X11 server unless instructed otherwise?

Then again, Apple has removed X11 support from Mountain Lion (10.8), referring X11 users to the open source XQuartz. I have no idea what the XQuartz installation is like, though it may be similar to the older Apple server.
