Not that easy, revdep-rebuild doesn't work either (dev-db/knoda is missing only in kde-sunset) By the way, revdep-rebuild re-emerges many too many packages, since it re-emerges all packages which depend only indirectly on the missing library. Furthermore the libraries are not missing since the have been kept by emerge ( => set preserved-rebuild) Thanks, Helmut. -- Helmut Jarausch Lehrstuhl fuer Numerische Mathematik RWTH - Aachen University D 52056 Aachen, Germany
