Before beginning to experiment with rebuilding KDE, I installed and configured Distcc and CCache. Here's a little HOWTO I wrote about the subject:
I'm currently using a cluster of three Intel Core 2 machines. Two jobs per machine and two CPUs per machine means I can build with NUMJOBS="-j12", which results in fairly acceptable speeds. Takes an afternoon of fiddling around until everything works, but it's worth the sheer gain in speed. Also useful for building Firefox or Thunderbird ESR and similar beasts.
