+      In the case where there is only one package, which provides either a native version where available or a bytecode version otherwise, the dependency on <varname>ocaml-base-nox-&ocaml-version;</varname> should be added only when the package is built in native mode. For example, the <filename>debian/control</filename> of <filename>approx</filename> contains:
