zombie entries reporting after ecleaning

Hi,

I want to keep my portage clean and sometimes run cleaning utils like eclean. But some minor disadvantages prevent this.

After running:

It tell you your tree doesn't have the ebuild dev-util/perf-3.8 while that package is install in your system.
You can fix that by upgrading "perf" to newer version your tree have (or remove it, blabla usual warning here...)

if the program is install (like perf) and you have a new version in tree, portage will report it when emerge -u world if perf is in your world.

if not in world, portage will only report it if emerge -uD world (and someone depend on it)

not in world, nobody depend on it : emerge -u perf. In this case, it will also appears if you emerge --depclean -p as it is install but nobody need it.

If it's a runtime dependency of someone, you will see it if you add the with-bdep

And if there's no more perf version in tree, portage will output at end of every emerge query that "perf is install but not in the tree" (well a similar output but i can't remember the exact one).

For your perl : they are all virtuals, so if no real package exists that use them anymore, --depclean will catch them. (see not in world, nobody depend on it case)

Then again, you may not want to. If the only reason you need a particular package is to build something you actually want—and the thing you actually want is up to date—then what benefit to you does updating that dependency bring? Portage's default to not rebuild out of date build-time dependencies if the packages that need the dependencies are themselves up to date is sane, I think.

John ... indeed, its not in any way necessary, and could even be seen as wasteful, but then there are situations like the above linked thread where there was a (perhaps confusing) issue with 'eclean-dist' that was resolved by updating a few virtuals. I have --with-bdeps=y as generally it doesn't add very much in the way of additional builds (at least on stable) and I would prefer any build deps to be up-to-date ... but of course that is entirely at the users discretion (and the above was offered as "preventative").

best ... khay
