Yes, the post-destroot-check is intended to find this kind of hidden
dependencies and report them. Introducing dependencies automatically
without manual interaction isn't really possible as it requires changes
to the Portfile which might be too complex for an automated task to
succeed. So this should be left to the maintainer.
