libglx.so is the X interface to OpenGL.
libGL.so is the actual implementation of OpenGL function calls.
You need both. libglx.so should be in /usr/X11R6/lib/modules/extensions, and libGL.so should be in /usr/lib.
Actually, if there's a libGL.so in /usr/X11R6/lib, then change its name or get rid of it completely, that one is part of Mesa.
Edit: what does xdpyinfo list for running extensions?
