I believe the idea was to use an OCaml SCL for this, and then when the
softwarecollections.org became a CentOS SIG, the virt SIG could depend
upon it.
I've been working on this here:
http://copr.fedoraproject.org/coprs/jonludlam/ocaml402/builds/
and here:
https://github.com/jonludlam/ocaml402-buildroot
I had some initial feedback from the SCL guys and have incorporated
that, and the packages have had some testing by us, Jane Street and
OCamlLabs. I think the next step is to do whatever is necessary for
the SCL to become an 'official' one.
