depclean only removes packages that it knows for a fact are no longer needed. This means - not in world - not linked to by anything - not depended on by anything "not in the tree" is not part of that list. If you have a package in world that is not in the tree anymore, depclean will leave it as is. It will remove ancient mere deps that are somehow still lying around though -- alan dot mckinnon at gmail dot com
