Ah, thanks for letting me know about this Pierre. I was in a rush to get
that
demo online so I built it on my laptop, which at the time was still running

Mesa 3.0 -- before they changed to the new library name standards. I
usually build on my desktop machine, which is up to date.

Right now, only the Win32 client links OpenGL dynamically. I don't do it
on the X client for two reasons: a) there's really no point that I can see,

since "libGL.so" has become a standard, b) I couldn't make it work. Here's
what would happen:

1) at startup I load libGL.so and libGLU.so

2) I make a bunch of gl...() calls, everything works fine

3) I try to call a glu...() function, say gluPerspective()

4) gluPerspective() tries to call glFrustum() and then

5) segfault...core dump...

It appeared that the linker was not properly putting gl() and glu()
together.
I posted some messages around USENET with no response, and then I
figured I'd yank it because of (a), above.

Anyway, that's the long answer. I promise never to build against an old
version of Mesa again. If you build from the sources you should be okay.
