I recently installed KDE 3.4 successfully (I did this by putting each
required module in package.keywords with ~x86). I tried to unmerge kde
3.3.2, yet when I did

emerge -C =kde-3.3.2

I received an error that no packages were listed. Yet, kde 3.3.2 no longer
shows up if I do

emerge -Cp kde

only 3.4.

All the files are still there in /usr/kde/3.3

I did an emerge --depclean -p and two expected kde modules showed up.
ldeaccessibility and kdewebdev. I know accessibility is optional, and
webdev is being held due to a bug. But the 3.3.2 versions were unmerged
successfully.

My question is, can I safely delete the entire 3.3 tree or is there a
different unmerge command for the meta package kde?

Thx.
