[solved] I want back to the fresh install

[otey]

This is probably my 5th reinstall. And I am kind of tied of doing it from scratch.
I was emerging gnome-light with the flags "gnome gtk -qt3 -qt4 -kde cdr dvdr alsa" in my make.conf and USE="firefox apache2 beagle" in front of 'emerge gnome-light'

Then suddenly my compilation stopped when installing some package that required cairo with the png flag on. I reemerged cairo with USE="png" and emerged the remaining packages of gnome-light.
Then compilation stops again while compiling some blablabla package. No explanations, no nothing.

Long story short: I want to go back to the fresh install. With only the stage3 apps, coldplug, and the rest of the software from the gentoo-amd64-handbook. Then I can start agan, using a manual or something.

Bottomline: How do I remove the packages and their config?

for file in `cat /var/lib/portage/world`; do emerge -C $file; done might do the trick, but just starting from scratch with a stage3 is faster and most likely more predictable.

Thanks a lot. I'll start from scratch again then. I get faster every time
