[I don't know much about OSX nor about ocaml on OS X, but..]

It sounds like lablgtk is not installed in the default location (normally 
it is installed where the ocaml libs are, in a directory called lablgtk/).

Ie on my system I have the caml libs in /usr/local/lib/ocaml, and lablgtk 
is in /usr/local/lib/ocaml/lablgtk. This lablgtk dir should contain many 
files including gObj.cmi, which is the first one which is searched for 
below and gives the error.

So the simplest thing would be to figure out where lablgtk got installed, 
and then modify the Makefile 
(the line GTK_DIR = $(LIB_DIR)/lablgtk ) to point to that dir. Or you 
could uninstall lablgtk and then reinstall in the standard location.

Hope this helps

Henri
