Thanks very much for the information!

Is it possible to link to the Mesa drivers without modifying the code?

For example, I'm hoping to link EDuke32 (game engine) to Mesa but I'm not
familiar with the code and I thought maybe I could just change the makefile
(or linker flags?) to link Mesa instead of the Apple OpenGL framework.
