I went back and did a make clean and perl Makefile.PL again, and
noticed the following --
WITH_3D: Looking for xdpyinfo to check GLX .
WITH_3D: Found xdpyinfo, now checking for GLX extension
WITH_3D: Found GLX (1 match)
WITH_3D: Trying OpenGL initial OPENGL_LIB configuration -><-
Trying libGL...
YES
WITH_3D: Success using -L/usr/X11R6/lib -lGLU -lGL -lXext -lX11 -lm
WITH_3D: Set WITH_3D => 1 and build OpenGL and TriD
skipping build of TriD::OpenGL(Q) modules - unable to find libs
Writing Makefile for PDL::Graphics::TriD::Rout
Writing Makefile for PDL::Graphics::VRML
Writing Makefile for PDL::Graphics::TriD
Writing Makefile for PDL::Graphics::PGPLOT::Window
Writing Makefile for PDL::Graphics::PGPLOT
Writing Makefile for PDL::Graphics::LUT::tables::DATA
Writing Makefile for PDL::Graphics::LUT::ramps::DATA
Writing Makefile for PDL::Graphics::LUT
Writing Makefile for PDL::Graphics::IIS
So, it seems OpenGL is missing even though libGL is present. Do I have
an unusual configuration, or an unusual configuration is required for
PDL::Graphics::TriD to build on Mac OS X?
