OpenGL GLX Extension for Tiger/Panther

I have Panther installed on my laptop and I'm able to ssh (with X Forwarding) into a server to run an opengl application. However, when I try and do that same thing using Tiger, I get errors about

Xlib: extension "GLX" missing on display "localhost:10.0".

I have X11 running in both instances so I can't figure out why I would be getting this unless I am missing something from Tiger.

Any ideas?
