After emerging gcc-3.2.1, python2.2 is not my friend anymore. It complains about not finding libstdc++.so.5. Copying /usr/lib/gcc-lib/i686-pc-linux-gnu/3.2.1/lib* to /usr/lib/ resolved the pb. But that is not the best way I guess :) I think the pb lies in the gcc-3.2.1 ebuild.
you need to re-emerge python after upgrading your gcc. you'll need to do this for any package which linkes to the previous gcc's libstdc++
It won't work, since those lib are not in the path. That's why I copied them _in_ the path. And btw, you can't use emerge when python doesn't (hint hint). But I must be wrong.
