Thanks for the info, that's interesting. I solved my problem by digging
up a binary package for OCAML 3.x. But it was not ideal, I think it was
a 8.3 package when was on a 8.4 system. Also, it was the old pkg
format, but a pkg2ng brought it into line with pkgng. It's great that
the new pkgng doesn't block the old packages, and even greater that we
can pkgng after the initial boot-strapping.
How would dependency resolution be affected by your suggested method?
The context of my issue was that I needed a unison built with OCAML
3.x. I would have thought that the port for unison232 would depend on
OCAML (as a build dependency) and thet would pull down OCAML 4.x. So
despite the OPAM provisioning OCAML 3.x, it would require some hacking
to get it to build unison232.
In the future, I may provision a FreeBSD 10.x server, and I will not
find a binary package for OCAML 3.x. Idealy, the OCAML devs should have
allowed for backwards compatability, like being abl e to create a 3.x
database. BTW, I don't know anything about OCAML, other than it's
needed by unison.

If you are really in need for the 3.x version of OCaml compiler, you
may want to try OPAM [1]. That is the ocaml-opam package [2] in the
FreeBSD repositories.
Although OPAM is dubbed as a "package manager", it can actually
manage
different compiler versions, using its "switch" command [3]. Then
you
could install OCaml packages atop that compiler separately, isola
ted
from other instances, giving the advantage of working with multiple
OCaml versions at the same time.
