In the second case, it quite reasonably assumes that the OCaml which has been installed is the one the OCaml developers intended which includes its compiler-libs package. Given that opam depends on ocaml, it should also depend on ocaml-compiler-libs, therefore. What you or the ocaml developers assume does not matter: what matters is how the package works. If you do not understand the question and can not provide the answer, I can see why the maintainer made his choice: he probably never used the packages, just ran any tests included. It appears that neither ocaml nor opam use ocaml-compiler-libs, otherwise the cygwin build and packaging software would include it, so which package in the ocaml suite actually binds the ocaml-compiler-libs to do its job, or does that package just provide dynamic libraries which are expected to be present when anyone runs ocaml programs? In which case users would be expected to manually install the package ocaml-compiler-libs. -- Take care.
