[gentoo-user] depclean question

[james]

OK,

So I just updated one of my system and all went fine.


I have not cleaned things up in a while, so I thought
I'd see what depclean says, know that I'm using kde4
and sets.....


So I get a huge list, including lots of kde-base 4.2.2 packages.


Hmmm, something is not right.
'emerge -uDNvp world' reveals nothing to update, yet depclean what
to remove lots of kde-base/<atom>-4.2.2 packages. Here's one example:


emerge -pv depclean shows this entry
<snip>
 kde-base/libkdegames
    selected: 4.2.2
   protected: none
     omitted: none


OK eix shows this:
kde-base/libkdegames
     Available versions:
        (3.5)   3.5.9 ~3.5.10
        (4.2)   (~)4.2.2 (~)4.2.3    
     Installed versions:  4.2.2(4.2)(10:10:14 04/28/09)

Now emerge what to update it:

emerge -pv libkdegames

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild     U ] kde-base/libkdegames-4.2.3 [4.2.2]


What am I missing here? Shouldn't the upgrade or world
pick up the the need to upgrade these packages, or
do I need some syntax to check my (kde 4) sets to see if
any of them need updating? (missed something here).


And why does depclean want to remove all of these kde 4
packages?  Surely, I do not have to put them
all in the world file? Use something other than depclean
with sets?


confused,
James
