Yes. About the main question, I asked this a while back. This thread should explain what is going on. https://sympa-roc.inria.fr/wws/arc/caml-list/2011-02/msg00144.html This lead me to write a small patch to glMlite, which I attach. As this patch is OS X specific (the current build system is targeted for Linux), it has not been incorporated upstream. I have not have found the time to do a "universal" patch yet.

I attach another patch, very straight to the point, but not of the most refineds aesthetics, still to the same makefile, about paths to libjpeg and it's headers files. (so in one thread on the ML archive we have all patches to build glMlite on OSX) sorry, I was mixing the GL.o of glMlite and some kind of /usr/lib/libGL.so in my previous email. would have spent half a day on it or more without yours.
