Comment 4 for bug 402710

In IRC I was pointed to:
https://bugs.edge.launchpad.net/ubuntu/+source/ocaml/+bug/387943
that request a blacklist insertion for ocaml package.

Now the main reason to blacklist ocaml has dropped, as Debian has nearly completed 3.11.1 transition.
So, we need to request an archive-admin to remove ocaml from the sync blacklist.
