It's unfortunate that Mesa sometimes gets dumped into /usr/X11R6/lib,
instead of /usr/lib where is belongs.  The simplest, most pragmatic
solution is:

  ln -s /usr/X11R6/lib/libGL.so.1 /usr/lib/libGL.so
  ln -s /usr/X11R6/lib/libGLU.so.1 /usr/lib/libGLU.so
  ln -s /usr/X11R6/lib/libglut.so.3 /usr/lib/libglut.so

...which is where Mesa is *supposed* to install.
