Hah! I had the exact same problem.  And I solved it in the dumbest possible 
way: running the exact same emerge command repeatedly until the error went 
away.  I *wish* I knew what the root cause is (actually, no, I don't), but 
that worked on two different systems.  It can take a few retries, though 
(three on my laptop, IIRC, but just one on my desktop).
