emerge --db-rebuild? [emerge update anomolies]

In my rescue operation I'm seeing some interesting results that is reminiscent of some that I saw recently on my workstation.

If I emerge -p, and name a specific package gentoo will detect the old one and say its either [R] or even [U]. However if it shows up with a [U], and I try to do a regular emerge -pu world, the package does not show up.

I know when this happened in RedHat there was a db-rebuild option that solved this kind of thing. Does Gentoo have something simular?

If that package was merged as a dependency of another package, it won't be in your "world" file, so emerge -pu world won't usually pick it up (except if the package that depends on it now requires a higher version).
Try "emerge -pu --deep world". That will look for updates on dependencies too.

These aren't dependancy anomolies. For instance if I do a emerge -p openldap on my machine right now I get...

We agree.

emerge -p openldap will look to see if openldap is installed, and if there's an update available or not.
emerge -p world will look at all the packages listed in your world file (/var/cache/ebd/world, or something like that), and see if there are updates for those packages.

If you first installed openldap by issuing explicitly "emerge openldap", then openldap should be in your world file and thus should show up in emerge -pu world.
If openldap was first installed by 'emerge package-that-depends-on-openldap', it won't be in your world file. But if "package-that-depends-on-openldap" (which is in your world file) has a new version, which requires a newer openldap, then openldap will get updated if you emerge -pu world.

[Not sure this is very clear, but I think it's correct at least :wink:

Yeah, although I did happen to have emerged it directly in the beginning I think we agree what is going on.

I suppose that rebuilding a world file would be pretty counter-productive since it would probably fill it with all the dependancies and bloat it. Right now I'm just emerging everything that I remember is on the machine, which is probably the best way to fix it, but having a world file rebuild would have been helpful.

I think in the future I'm just going to backup the world file.

Try this:

Hmm, interesting. Same results as the other try, it still picked up an embarassingly small amount of the packages I have installed.

Thanks to everyones help I have warm fuzzies about Gentoo (no really).

But inspite of everyones help, I found the answer to my question really is the utility packaged with portage called...
