I should also add a reminder of the Golden Rule of VirtualGL:
Try to run the application without VirtualGL first.
---------------------------------------------------
I suspect you're going to discover the problem either in the process of
trying to run /opt/VirtualGL/bin/glxspheres without VirtualGL or in the
process of running 'ldd /usr/lib32/librrfaker.so' to see what
dependencies of VirtualGL are missing.
