This is due to broken/incomplete OpenGL headers on your system.  I've heard the
Solaris lacks a GL/glext.h header.  If this is the case, then SDL is using
a built-in glext.h file from http://oss.sgi.com/projects/ogl-sample/registry/

The SDL-provided header has all the necessary symbols, but they are only
defined if your GL/gl.h file does NOT do something silly like:

#define GL_ARB_multitexture

Unfortuantely, there is nothing we can do from ioquake3 to detect this breakage.
The only option would be to include full OpenGL headers in the ioquake3 SVN for
use with broken systems which may happen.

In the mean time, check your gl.h file for that define and try commenting it
out.
