Debian policy is that any virtual dependencies must also have an
explicit dependency. In your case it would be something like
Requires: phonon-backend-gstreamer | phonon-backend
If the virtual dependency is already satisfied then nothing happens,
but if not phonon-backend-gstreamer would be used to satisfy it. This
works fine for package dependencies, but I'd imagine file-based
dependencies would make things more awkward.
