[gentoo-user] kde:3.5 how to phase out

[Helmut Jarausch]

Hi,

I'd like to phase out KDE:3.5. One reason is, that I cannot install
both, 3.5 and 4.2 without using 'prefix'.

For doing so, I need to find out which (installed) packages use which
parts of KDE:3.5. Is there something better than unmerge all of KDE:3.5
and let revdep-rebuild find out.

Furthermore, how to unmerge all of KDE:3.5, e.g. 
emerge --unmerge kde-base/kde-meta:3.5
does not work.

Many thanks for a hint,
Helmut.
