I'm glad it worked! If you don't have the latest OpenGL and OpenGL::GLUT, it won't build the TriD stuff. Sadly, to get it to do so, you'd have to rebuild/install the whole thing after installing those two. I'd be grateful for feedback on whether that worked, if you do try it.

I remember being rather put off by the concept of a "PDL course", and never actually did it explicitly. I'd say though that these days I'm somewhat familiar with the whole thing. But a great starting point is just to run the demos; list them with the demo command in perldl. They tell you what they're doing as they go along. Again, I'd be very grateful for feedback on things you think are bad, unclear, or confusing, or could be better.
