I have just rerun the nurb program on another machine which
is running the distribution version of XFree86 4.2.0
which I downloaded as source and built on May 20, 2002.
Accelerated rendering is on and working through an
r128.
This version appears to build libGLU 1.3 along
with Mesa 3.4.2.
The problem also persists there. So I think that the
libGLU version is not the key -- but that probably
Mesa 4.x may well contain the solution.
Thanks for the help,
Mike
