At least my version does. > Maybe that happens because the dev-perl/ version of the package is > automagically created? No, no automagic here. dev-perl/Class-Base was added to the tree on Jun 23. perl-gcpan/Class-Base-0.03 is obviously an ebuild created by g-cpan for the same package as dev-perl/Class-Base. Both install the same files. So there is a collision. You just have to clean your perl-gcpan category regularly.

(In reply to comment #2) > (In reply to comment #1) > > You just have to clean your perl-gcpan category regularly. > > What does it mean in general (to prevent such future collisions)? Good question. But I don't think i've a good answer. - File a bug so you will (probably) see when a package is added to the tree. => We will get a lot of bugs for packages that will never make it into the tree :( - Move the package from perl-gcpan to dev-perl? => Doesn't help if we'll give it a different name. - Try to get the package in a properly maintained overlay, like perl-experimental or sunrise => Likely someone else will do the work (So we are back at point 1, file a bug) > I will unmerge the perl-gcpan/Class-Base-0.03 if I got it right. Yes, unmerge (and remove) perl-gcpan/Class-Base and fix the dependencies of all other packages that depend on perl-gcpan/Class-Base (s,perl-gcpan/Class-Base,dev-perl/Class-Base,).
