Please could either the opam or ocaml package be updated to depend on ocaml-compiler-libs. Fixes https://github.com/ocaml/opam-repository/issues/16457. Debian/Ubuntu and Fedora both also have ocaml-compiler-libs packages, but it's installed by their ocaml package as well. Arch chooses not to do this, having packages like ocaml-findlib expressly depending on ocaml-compilerlibs and so also has its opam package depend on ocaml-compilerlibs. As both an upstream OCaml and opam maintainer, I don't mind which package has the dependency, but if opam is installed, please can any system-installed ocaml definitely be "complete"! Many thanks, David
