Everything as up-to-date as possible (run with --verbose to show unavailable upgrades).
However, you may "opam upgrade" these packages explicitly at these versions (e.g. "opam upgrade ocaml-base-compiler.5.4.0"), which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.
