This happened to me, too.  It was also reported as a bug to the Gentoo
bugzilla.  The mechanism for the bug was quite involved, but the
solution was straightforward.  That was to replace

    VIDEO_CARDS="radeon"

with

    VIDEO_CARDS="radeon r600"

in /etc/portage/make.conf.

The "r600" bit is actually documented in the "Radeon" article in the
Gentoo Wiki, though I suspect it is relatively new.  If I were you, I'd
check in that article that my card actually does, literally, need
"r600", and not something like "r750".

If this doesn't get your emerge working again, have a look at that bug
report.  (Search for "mesa" and look at the most recent bug it finds.)
