I have the same problem with pbuilder... apt prefers packages from
experimental over those from sid, while it should be the contrary, and
the dummy package for build-dependencies would make sure the build
dependencies are downloaded from experimental when needed (that's what
versioned dependencies are for, aren't they?).
