Yes, what Neil sagely advised. :-) I suggest you make it a rule to always run emerge for any individual package atom with -1, unless you *really* intend to install such a package yourself and it has not been already installed as a dependency for other package(s). If you do not use -1 the package you emerge will be added in your world file and then you could end up fighting against portage sooner or later. Imagine a hypothetical scenario where one day CUPS is deprecated and replaced by the oh-so-marvellous latest and greatest CUPS-ng. You try to update your system, but come up against a blocker because the recently deprecated old CUPS now clashes with CUPS-ng. The old CUPS is in your world file, because you added it there by running emerge without -1 and consequently portage cannot override your choice and unmerge it to replace it with CUPS-ng. Portage will now throw a wobbly, alerting you to a blocker you must resolve yourself. This is why you were advised in previous messages related to the recent python updates to make sure among other things no python packages have inadvertently ended up in your world file. Unless you're a developer with specific python requirements, you would not want python which is both a @system set and potentially @world set dependency to end up in there. --nextPart1846072.PYKUYFuaPT Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part.
