Notice that this is really not nice for a bugfix release, since this means we
have to rebuild all of the ocaml related packages on all arches, which may
take us month and such. Maybe we would be better off just backporting the
non-breaking fixes ? Maybe in future this situation could be somewhat improved ?

Oh, well. ...
