You need to do one of the following:

1. If your X server supports GLX, but it isn't enabled, then enable
it; for XFree86 4.x, you need the line:

    Load	"glx"

in the "Module" section of XF86Config.

2. If your X server doesn't support GLX, replace your X server with
one which does, or

3. Replace your GL library (libGL.so.*) with one which implements
OpenGL on the client side (e.g. Mesa), eliminating the need for the X
server to support GLX.
