What gives "emerge -p --depclean" ? What gives "emerge -DNu world --with-bdeps=y" ?
(In reply to comment #1) > What gives "emerge -p --depclean" ? emerge -p --depclean * Always study the list of packages to be cleaned for any obvious * mistakes. Packages that are part of the world set will always * be kept. They can be manually added to this set with * `emerge --noreplace <atom>`. Packages that are listed in * package.provided (see portage(5)) will be removed by * depclean, even if they are part of the world set. * * As a safety measure, depclean will not remove any packages * unless *all* required dependencies have been resolved. As a * consequence, it is often necessary to run `emerge --update * --newuse --deep @system @world` prior to depclean.

It's a little irritating, since without some packages won't be updated over a long time. And it's also a little confusing to the --deep option.
One can argue for both --mith-bdeps=y and =n. If you want y you could put it in your EMERGE_DEFAULT_OPTS.
