I have KDE 3.5 and 4.1 installed and am trying to upgrade to 4.2. I'm getting

kde-base/kdelibs-4.2.0)
Is there an issue with 3.5 and 4.2 being installed together? Is the above
block a known issue that's being worked out as 4.2 is integrated into the
stable tree? (I was unable to find a bug filed on it or any other hits on
Google.)
I recommend that you edit your world file by hand
(/var/lib/portage/world) and remove everything from in there that you
wish to unmerge. Then run "emerge -p --depclean" and take a good look
at the output. Put in the world file every package listed that should
NOT be removed. When everything looks fine, do the final "emerge -a
--depclean".
Take care though after that not clutter your world file again. That
mainly means that if you emerge some dependency of a package manually
(for whatever reason) do so with the -1 or --oneshot option of emerge.
Note that you can put slotted packages in the world file. For example
if all you have in there is "kde-base/kdelibs" and you remove it,
depclean will remove both KDE3 and well as KDE4 libs. Simply put
"kde-base/kdelibs:3.5" in the world file. depclean will not remove the
3.5.x versions that way. Personally, I keep the 3.5 slots and an
unslotted version:
kde-base/kdelibs
kde-base/kdelibs:3.5
This will provide easy updates to future 4.x versions but will not mess
with 3.5.
I find that having a clean world file makes package management in Gentoo
a lot easier :)
