The GTK examples were written for LinuxPPC.

GTK isn't distrubuted as part of OSX (though you can use things like
Fink or Darwinports to install an X11-based version.)  I think that
there's been some progress in creating an Aqua-native version, but
haven't followed this too closely.

If you -really- want to, you can try to use the interface translator
to produce "cdb" files for GTK/GDK on OSX.  GTK 1.x isn't particularly
thread-safe, and I'm not sure what you'd need to do to to really be
able to exploit GTK 2.x under OpenMCL: the header files make heavy
use of the C preprocessor, and it's not clear how much of that can
get automatically translated into something useful.

At one point, I accidentally checked in a "real"
"ccl:OpenMCL.app;Contents;MacOS;dppccl" ; it takes CVS quite a while to
either check this out or figure out that that wouldn't be a good idea.
I replaced the copy that's in the repository and it seems that I can
update working copies without confusing CVS.

Until you're more comfortable with OpenMCL, you probably want to mostly
ignore the development ("bleeding edge") CVS tree.
