Hmmm - what distro do you have?

I'm suprised that you'd need a particular GCC/Glibc unless your system
is *very* old.

Yes - or you have it installed in the wrong place.

You should have the following files:

   /usr/include/GL/gl.h
   /usr/include/GL/glu.h
   /usr/include/GL/glut.h

   /usr/lib/libGL.so.<version_numbers>
   /usr/lib/libGLU.so.<version_numbers>
   /usr/lib/libglut.so.<version_numbers>   ...or /usr/lib/libglut.a

You should *not* have other versions in other directories - you should
not have any libMesa<anything>'s...unless they are symbolic links to
the files above - or vice versa.  You should use the Linux 'find'
command to search out all the strange versions stuck in places like
/usr/local/lib, /usr/X11R6/lib and so on.  If you don't do that, you'll
find that some programs pick up the "correct" OpenGL/Mesa and others
will find ancient versions that have the wrong drivers or something.

Be *RUTHLESS*!

Weeeeelllll.....*maybe*.

GLUT is normally distributed with Mesa - and is probably on your
Mandrake distro.  Why it's not installed - I don't know.  Maybe
it *is* installed - but since the GLUT header #include's the
OpenGL headers, that could be enough to screw up the ./configure
script into thinking that GLUT isn't correctly installed.

You should also be able to get it from http://www.opengl.org - or
with Mesa at http://www.mesa3d.org...and as you said, "freeglut"
can be a reasonable replacement - get it at http://freeglut.sourceforge.net

However, freeglut won't install if your OpenGL is broken.

I can imagine!  But having your OpenGL/Mesa correctly installed is
an ESSENTIAL first step.

When you think you have it right - run some Mesa sample programs and
be sure you are actually getting hardware accelleration.  Once that's
working, try again with PLIB (and 'freeglut' if you want).
