[removed build log & host configs]

I am having observing the same problem too.  I updated to r317713 & rebooted  
the r317713 host, then I tried to build a release & it failed with the same 
errors.

I checked out a clean copy of src at r317713 into /tmp, removed /etc/make.conf 
& /etc/src.conf & tried again, tho, still the same problem.  I have also tried 
buildworld on a r317820 check out, however, this also results in the same 
failure.

My host r317713 was built with:
