Hello Jeffrey,

here's a simple build script:

MLLIBS=/opt/godi/lib/ocaml
GL="$MLLIBS/pkg-lib/lablGL"
EXT="$MLLIBS/site-lib/extlib"
OSX_GL_DYLIB="-dylib_file /System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:\
/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib"

ocamlopt -I $EXT -I +lablgtk2 -I $GL -ccopt "$OSX_GL_DYLIB" -o glplot \
extLib.cmxa lablgtk.cmxa lablgl.cmxa lablgtkgl.cmxa gtkInit.cmx glplot.ml

you firts must compile gtkglarea 1.99 and then configure/rebuild lablgtk2 to
enable gtkglarea support.

I've yet been able to bypass the OSX X-Window layer using:
http://developer.imendio.com/projects/gtk-macosx
I was not able to compile gtkglarea-1.99 against gtk-macosx, and given
up for now.

maybe it's this you're refering:
