Having completed the upgrade I noticed that a few packages are being called up 
for removal:

 sys-apps/dmidecode
    selected: 2.10 
   protected: none 
     omitted: none

I can't think of it being a dependency - did I emerge it and forgot about it?


Anyway, this confused me more:

  kde-base/okteta
    selected: 4.4.5 
   protected: none 
     omitted: none

okteta is not my world file.  So something brought it in.  It was not updated 
to v6, instead when I try to update it manually is asking for a second slot 
... is this normal?
=====================================================
# emerge -uaDv okteta

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

Calculating dependencies... done!
[ebuild  NS   ] kde-base/okteta-4.6.2 [4.4.5] USE="handbook (-aqua) -debug (-
kdeenablefinal) (-kdeprefix)" 5,933 kB
[uninstall    ] kde-base/okteta-4.4.5  USE="handbook (-aqua) -debug (-

[blocks b     ] kde-base/okteta:4.4[-kdeprefix] ("kde-base/okteta:4.4[-
kdeprefix]" is blocking kde-base/okteta-4.6.2)

Total: 1 package (1 in new slot, 1 uninstall), Size of downloads: 5,933 kB
Conflict: 2 blocks
=====================================================

Why is this happening?
