With same versions and date as above and OS X 10.7.5 Lion, I installed
glxgears and it worked fine.  So do Kubrick and KSudoku (3-D Roxdoku
options), two Qt-KDE based programs that use OpenGL.

I have glxgears at 8.1.0_0 (binary) and KDE at 4.12.4.  My X11 server is
XQuartz 2.6.5 (xorg-server 1.10.6).
