Yes and that's an "interesting" but slightly separate issue. Since
binaries are statically linked to OCaml / glue code but dynamically
linked to C libraries it turns out to be not as much of a problem.
(See virt-top where I've shipped a binary of this OCaml program which
runs on many different platforms -- eg. Debian, Fedora and Ubuntu).
But if RHEL customers start to ship OCaml libraries then we may be in
for a bit more, erm, fun.
