THANK YOU DUNCAN!

YOU FIXED IT.
or better, i fixed it, but i would have been lost without your help. the 
quickpkg thing did the trick.

first i was in doubt, cause quickpkg is not on the livecd fs, but then i 
started thinking, and then i untared stage and portage and made the package.

first i untar'ed the package over /etc, but the i did it on root and it 
worked.

once again THANK YOU, you saved me a LOT of work!
