Unfortunately, on MacOSX ocamlbrowser only works properly with the X11
version of Tk (which is very easy to install.)
I tried several times to make it work with the Aqua version, but was
never completely successful.

Most other LablTk programs seem to work properly with the Aqua version
of Tk, so YMMV.
