Judd-
Thanks for the testing. I had been assuming that
the problem was missing fonts on the problem systems
but your check seems to eliminate that possibility.
I'm sort of leaning towards a version skew problem
either between multiple GLUT and FreeGLUT installs
on the same system or perhaps between 32bit and
64bit versions of the same or both... Here are some
questions/ideas to try:
(1) Do you have both GLUT and FreeGLUT on your system?
If so, freeglut.h might need to be substituted for
glut.h in OpenGL/glut_utils.h
(2) Do you have both 32 and 64 bit libraries on
your system? If so, I would doubt that a 32-bit
pointer value would match the 64-bit stuff
(3) Could you try compilng PDL-2.4.4_136/bitmap.c
using the LIBS and INC flags from OpenGL::Config.pm?
If that fails then the problem is likely some
type of version skew between headers, libraries,
or both.
(4) Could you send me your OpenGL-0.59/Config.pm file
as well as the output of perl -V? Maybe I can
glean something from there.
Apologies for the lack of insight. It is remakably
difficult (he remarks) to debug a problem that one
cannot reproduce.

Perhaps, but my money is still on configuration
issues since the rest of the module is just bindings
to a C library.
Look forward to hearing from you.
Cheers,
