7.0-BETA1 AMD64 buildworld error

[Indigo 23]

I have updated sources as of Oct 25 and I tried building world
(7.0-BETA1 AMD64), but I keep receiving the same error (see below) and
I'm not sure how to fix it.  I tried removing my sources completely
and getting a fresh copy as well as running make clean in /usr/src,
but to no avail.  Anyone have any ideas?
