Hum, ... I am not sure what non-free-ness you mention here, but i believe that
as of today the distribution of ocaml is covered by a free licence, at least
considered so by debian, and you know what that covers.

Nope, clause 4 of the QPL clearly grants you rights to distribute not only the
binaries of ocaml but also modified forms of said binaries, provided they come
under the QPL, and clause 3 of the QPL provides you with the right to
distribute modifications in such a way as the original pristine tarball can be
clearly identified.

So, i would say your question is a non-issue.

Indeed, this is what the QPL clause 3 asks you, you should be fine.
