After executing 'emerge sync', a strange message is printed: ---8<------------------------------------------------------------- >>> Updating Portage cache... /!!! eclass 'GPL-2' in 'GPL-2' does not exist: ...done! --->8------------------------------------------------------------- It has been confirmed by two other users on the gentoo-user mailing list (<m3u1a338dq.fsf@arrakis.hashbang.de> and the follow-ups).
Should be fixed in the next rsync update but might only be in the one after that.
