Hmm, so "nonative" would be for ports that produce bytecode-only
programs, even on native archs? (No idea how many ports are affected.)
We could call it "bytecode" then, that would seem a bit more descriptive
than a plain MODOCAML_RUNDEP=Yes in a port Makefile.
And then MODOCAML_RUNDEP=Yes would be useful for ports that always
use lang/ocaml programs/files at runtime?

Here's the simple diff I had in mind yesterday, on top of Bjorn's diff.
It probably helps Bjorn with unison but it would require testing all
other OCaml programs, and bumping REVISION for a bunch of them.
Maybe not the easiest or safest approach.
I suspect that most people caring about OCaml in ports have thought
about this before, hopefully they can share their ideas. :)
