FWIW, Mesa 3.0 with Berhard Tschirren's Allegro driver compiles
out of the box, and Mesa 3.2 works with some very slight patching.
(the only thing that has changed from the driver's point of view is that
some of the sources have been renamed, and new ones have been added.)

It comes with a minimal GLUT that compiles practically everthing
available with the distro. (As well as 80-90% of the sample GL sources I
was able to find on the net.)

Also, Mesa will compile into the OS (off screen) driver, (just gotta type 
'sh configure' then 'make' and when you create a rendering context, 
just pass a linear buffer big enough to hold the pixel data (like an 
allegro bitmap, i.e. bmp->line[0]) and off you go. Only downside is 
you then have no GLUT.

It surprises me that there have been so many threads in this group over 
the horrors of Mesa and DJGPP when it is really quite easy. (esp. thanks to
Mr. Tschirren's work on 3.0 and earlier.)

(For the curious, I use djdev2.03 bnu2952 and gcc2952 with locally compiled
bash, sh-utils, and fil-utils just to make sure they were built with the
latest 
stuff.)
