removing old KDE3 packages

[Warren Liddell]

A lot of applications i have fail to compile and im assuming work
 correctly due to the fact i had KDE3 & 4 installed on my AMD64
 7.0-STABLE machine .. i have deinstalled KDE3, but a  lot of the
 dependencies form it remain, so my question is....

 1. How do i remove all the old kde3 stuff and leave whats needed for
 KDE4 behind

At the same time im coming across a lot of applications installed that still 
require that i have kdelibs3 installed rather then 4
