[gentoo-user] fsck + emerge => crash

[Loupy]

Hey all,

I got a power here, which after I had to run fsck... well there where
some troubled Inodes and I choosed yes to repair them.
So far so good, system booted well, but now I cannot emerge anything at all.

emerge --info tells me as normal user:
emerge: incomplete set configuration, missing set(s): "world" and "system"
        This usually means that '/usr/share/portage/config/sets.conf'
        is missing or corrupt.
as su I get a bunch of these messages:
Parse Error reading PROVIDE and USE in '/var/db/pkg/kde-base/libkdeedu-3.5.10'

emerge --regen tells me the same...

well, what would you advice me to do?
