I encountered an error during my regular "make buildworld" today that I
suspect is related to the above.

and things don't really get better after that.

CXX=clang++

(Only change in the above since 07 Mar 2013 -- ovcer a year ago --
was to comment out the PORTS_MODULES line for a while, then uncomment
it after x11/nvidia-driver was fixed).
I don't *think* there's much in make.conf that's relevant, but:

Ah -- my build machine finally(!) caught up with my laptop; also i386,
running:
FreeBSD freebeast.catwhisker.org 9.2-STABLE FreeBSD 9.2-STABLE #914 r263452M/263468:902508: Fri Mar 21 05:21:10 PDT 2014 root@freebeast.catwhisker.org:/usr/obj/usr/src/sys/GENERIC i386
/usr/src also updated to r263617, and encountered the same issues
as above. Its update history may be found in
<http://www.catwhisker.org/~david/FreeBSD/histpory/freebeast_i386_9.txt>.
Peace,
david
