Created attachment 407258 [details, diff] Patch extending support for paludis I created a patch for perl-cleaner which implements deselect-perlcore and update-virtuals for paludis. Because there is no paludis function which allows printing installed packages matching a given pattern, I added a call to grep to do the filtering. This also works with portage/qlist. The patch also changes the PMS_UPGRADE_COMMAND for paludis to include -U perl-core/* (-U is --permit-uninstall), because otherwise paludis refuses to uninstall perl-core modules causing the dependency calculation to fail.
This is in just-uploaded perl-cleaner-2.23
