Yes, you may unmerge kde 3.4.
I'm not sure that
    emerge -aC =kde***-3.4 (depending on what you emerged ; you can see that
with 'cat /var/lib/portage/world | grep kde')
, then
    emerge -aC depclean
will do it.

I remember having used 'equery list -d' to list packages that are installed
twice.
If you don't have equery, emerge gentoolkit.
Then, with a simple ' | grep kde' and ' | grep 3.4', you get the kde
packages to uninstall.
Note that you have to put a '=' before the packages to unmerge when you
specify an exact version.
NB : you also may want to delete the .kde3.4 folder in your home directory.
But first, be sure that all your settings are ok, and make a backup !

Cheers,

François
