well, it seems like your Xserver is missing the GLX (openGL for X) 
extensions. since Gem highly depends on openGL, it refuses to continue...

which driver are you using? probably your Xorg.conf needs tweaking.

do other openGL apps work? a good start is glxgears (if this doesn't 
work, chances are minimal to non-existant that Gem will...)

if glxgears do work, try setting the environmental variable 
GEM_SINGLE_CONTEXT to 1. (setting this variable can be considered the 
first voodoo to do when problems occur)
