ports directory names

Hello, I've downloaded crux 2.5 as provided by web site and installed on a i686 machine. while I was trying to use ports I have failed to use contrib.rsync file as provided. ports -u was failing to find "ports/crux-2.6/contrib". Only after I have changed the collection line to ports/crux-2.5/contrib I have been able to update the contrib ports collection (though still I'm trying to succesfully install rrdtool). Is there a bug/typo in contrib.rsync file ? Regards, Arif
