They are not duplicates they are called SLOTS And you have them for a reason - one thing needs package A version X, something else needs package A version Y. Usually, you can have only one, SLOTS let you have more than one that can co-exist. Don't worry about them, let them be. You need them. -- Alan McKinnon alan.mckin...@gmail.com
