Well, I don't know about necessary, but on my box, when I tried to
update from kde-meta:4.2 to kde-meta:4.3, there were a few blockers that
wouldn't let it go through, so I ended up unmerging 4.2, then emerging
4.3 (which took about 4-6 hours, but I have distcc set up between two
boxes, so that probably sped things up).  However, I seem to remember
that the blockers were with PyQt, Python and eselect-python; I hadn't
thought about it, cause I'm still not THAT experienced with Linux in
general, and Gentoo in particular, but the Python update was a Big Deal,
so perhaps updating Python before the KDE upgrade would have been a good
idea.  :-P  Granted though, I didn't use sets, so it may be a bit
different for you.

Oh, and I didn't touch my .kde or .kde4 folders during this process, and
as far as I can tell, it's still using all of my customizations...
