Thanks for that helpful info, I think I understand 
the "why" now, but still not the solution.

Turns out that I am working in a VNC display.  When 
the program displays to the machine's console X server 
it runs fine.  But when it tries to display to the VNC 
x server it produces the error.

Doing some searching did not turn up any clear (at 
least to me) answers.  I gather VNC doesn't support
the glx extensions.  I came across xf4vnc but that 
seems to be old and based on xfree86 and its not at 
all clear to me if it will work with fc6/xorg.

Has anyone else been down this path and have any 
advice?  Is it possible to have an OpenGL produce
output in a VNC display?
