I don't quite understand your question - opam is OCaml's package manager.
It can either compile OCaml itself from sources or use the OCaml installed by the system's package manager. 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.
