ocaml update to 4.01

[Jaap Boender <jaapb%kerguelen.org@localhost>]

Hello everybody,

I've just committed ocaml 4.01 to pkgsrc - revbumped all ocaml packages as 
usual. There could be some breakage (I've had to fix net/ocamlnet, 
devel/ocaml-lwt and devel/ocaml-batteries), so users of less-common ocaml 
packages might want to check that everything still works.

all the best,

  Jaap
