It should also be noted that running --depclean on a specific package *ONLY* removes that package. After depcleaning a specific package, you should run --depclean again to remove any dependencies of that removed package: emerge --depclean --ask -v cat/pkg emerge --depclean --ask The alternative (at least for packages not in a selected set) is to emerge --deselect cat/pkg emerge --depclean --ask This will, oddly enough, deselect the package from being wanted or "selected", allowing it to be depcleaned, along with its own dependencies, if no other packages depend on it. Both methods require two commands, so mostly there's no real difference; and in this case depcleaning python:$SLOT is probably better as it's essentially saying you want to explicitly remove it if it's not required; but for normal packages (or multiple packages - it's quicker) I personally prefer deselecting then depcleaning. Just my two small monetary amounts :) -- wraeth <wra...@wraeth.id.au>
