So, please check where these files came from by

qfile /usr/src/linux-2.6.31-gentoo-r6/Makefile

Have you installed this kernel 'by hand' i.e. outside of portage?

Check by uname -a   if you are not currently running linux-2.6.31-r6

If not, it's safe to rm -rf /usr/src/linux-2.6.31-gentoo-r6
and emerge it again.

Helmut.
