Hi Chris,
I just tried rebuilding PDL with TriD, and I am happy to report that
PDL::Graphics::TriD builds on my Mac without any problem (I am using
Mac OS X 10.6.4).
I got the following report (relevant to TriD) when making the Makefile
--------------------------
USE_POGL is set, will build TriD using OpenGL.
Graphics/TriD/Makefile.PL: using POGL for OpenGL bindings and compile options
Writing Makefile for PDL::Graphics::TriD::Rout
Writing Makefile for PDL::Graphics::VRML
Checking if your kit is complete...
Warning: the following files are missing in your kit:
Changes
Please inform the author.
--------------------------
I have no idea what "Chages" is... if I try to install a module called
"Changes," I get something called Alien::BWIPP
--------------------------

--------------------------
Nevertheless, PDL builds without any issues, as long as I make the
corrections to the Graphics/PLplot/Makefile as document earlier.
Another issue... I ran a few demos for TriD (just to make sure things
were working). I get the rendered images (charts) to show up in a
separate window, but then the program hangs. When I try to close the
window, (there is no obvious way to close the window and terminate the
program), I get the following error
-----------------------------
PDL> use PDL::Graphics::TriD
PDL> $a=sqrt(rvals(zeroes(50,50))/2)
PDL> imagrgb [0.5*sin(8*$a)+0.5,0.5*cos(8*$a)+0.5,0.5*cos(4*$a)+0.5]
(this is where I try to close the window that popped up with imagrgb chart)
