The gtkGL stuff looked pretty interesting, but I also ran into compile problems
with version .80.  Specifically, the configure script couldn't find the
gtk,intgdk, or MesaGL libraries, all of which are in /usr/local/lib.  I
have gtk 1.0 and Mesa 2.6; both seem to be installed correctly, since other
things compile with them.  I tried --with-GL-prefix and --with-gtk-prefix but no
go.  I looked  at the config.log and it had some messages like this:

...

glGetError()
; return 0; }

Hopefully you can help me by pointing out where I either have something
configured wrong, or where the configure script can be changed so that I can
compile gtkGL.  I don't know anything about autoconf really since I'm pretty
new to Linux, but my guess is that the problem is in the lines 

configure:2461:  gcc -o conftest -g -O2   -L/usr/local/lib
-L/usr/local/lib
-L/usr/X11R6/lib conf
test.c -lgdk   1>&5

because I don't see something like -lX11 where I would expect it.  Same thing
with the compile of the Mesa stuff.

It looks like a really cool package, I just wish I could compile it!
