Mesa, all by itself, does not implement the GLX X server extension.
For that, you'll need XFree86 4.0.x.  It includes Mesa and implements
the GLX extension.  If you have 3D hardware (like 3dfx) then you
can get hardware acceleration too.

If you don't want to upgrade your X server one solution is to
compile/install Mesa on your IRIX machine.  "Stand-alone" Mesa
will emulate the GLX API and effectively translate all your OpenGL
commands into ordinary Xlib commands which can be displayed on
any X server, with or without the GLX server extension.
