When I try to run GZDoom, I get the following error message in a dialog box:

"Unsupported OpenGL version.
At least OpenGL 3.3 is required to run GZDoom.
For older version of OpenGL please download the vintage build of GZDoom."

However, using some environment variables I learned about at the Mesa
project website, I got it to run on my computer *very* slowly with
software rendering.
