Dan was right about ld.so.conf. Like LD_LIBRARY_PATH, it only resolves
libraries at run time.  The gl.pc file is correct and it is in the
plg-config path, but the freeglut demos are quite old and don't use
the .pc files.

The are two ways I've found to fix this:

LDFLAGS="-L/opt/xorg/lib" ./configure ...


./configure ...

I think I will add the 2nd for for the educational value.  I don't
think we use it anywhere else.
