Thanks for the reply, Mark. This PI is on circa 1994 Irix 5.3. Nope,
this cut of Blender is IrisGL, so I don't think that's it.

Certain stock Irix 5.3 demos don't work. Launching the MahJong is fine,
so is the flight sim. Launching the mandelbrot fractal maker is a no
go--says 24-bit is needed. The Porsche driving sim. comes up but puts
up an error message that says "gconfig: not enough bitplanes for RGB
mode."
