In theory they are still around, but the program in question is no longer maintained, and the mac version never got the frame rate of the windows/linux versions, so it was never a big focus. The company's focus has shifted -- apparently their engine is more valuable for simulation companies than being used for a game engine. But: This program is not the issue. This is a plain X issue.

It might, however, be worth installing the macports version to see if it will run, and if so to compare with the startup scripts and permissions for the XQuartz version.

xinit is now a binary, not a script, so I can't do any comparisons.
I do need to get the XQuartz version running for this commercial program.
But the point is, XQuartz should be able to launch itself. Right? This version of X should still run, even if it is 4 years old, right?

I am starting X by running "xinit" (from the command line), and expecting it to do all the stuff needed to start up the X server.

The last time I used X was on sun nodes back at UCLA, and that was all it took there.

Never heard of it.
