 We already asked Gerd for the modfication some monthes ago and he did it.
 These are the rules followed by findlib to get the META file for a
 library foo:

 * Search in OCAMLPATH a directory that have a subdirectory foo in which
   there is a META file.
 * Search in OCAMLPATH a file META.foo. In this case, in the META file
   there must be the entry "directory" that specifies where the library
   is actually installed

 OCAMLPATH can be set as a shell variable; otherwise it reflects
 the entry path in /etc/ocamlfind.conf.

 So:

 1) We can put all the META.lablgtk, META.lablglade, META....
    directly in /usr/lib/ocaml
 2) We can put them in another directory and add it to the path in
    /etc/ocamlfind.conf. In this case, findlib helps again: you
    can add a "metadir" entry in /etc/ocamlfind.conf; when you do
    findlib install, findlib will automatically install the META file
    in the metadir.
 3) We can add /usr/lib/ocaml/lablgtk to the path in /etc/ocamlfind.conf
    and leave META.* into lablgtk.
