It is likely that lablgtk2 is not correctly installed on your system.
Did you checked for gWindow.cmi in `ocamlc -where`/lablgtk2 for instance?

To check your lablgtk2 installation, you can also try to launch the
lablgtk2 toplevel, with the "lablgtk2" command. Then you can type in the
sample code above directly in the toplevel. (But it is likely that
you'll get the same error message, since it means that gWindow.cmi is
not found).
