     * might not be able to download pom/gem for the calculated version. so it
     * would only make sense if the all the poms are generated as well and the
     * gem download just passes the request on to rubygems.org. BUT the latter
     * is difficult since there is not a proper "file not found" coming from the
     * rubygems server. . . .
