huh? Oh you mean problems setting up a testbed. If there is a time we can we can sync up I can help walk you through it. Can you email e off list?
If not, if you start with the livecd and follow the instructions http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?full=1 then you will have to install xorg-server, kde-meta, and then inkscape. I can send you my world build file from one of my machines, and that might make building the packages faster, but will be a lot more that you really need for a test bench.
