Building current no longer possible on 8.2, worked 7 days ago

Hey all,

I'm running the coverity builds/scan on a 8.2 VM, buildworld was fine 7d
ago, now it's kaput:

>>> Building an up-to-date make(1)
>>> World build started on Mon May 20 13:43:09 UTC 2013
>>> Rebuilding the temporary build tree
>>> stage 1.1: legacy release compatibility shims
