FreeBSD 10.0-CURRENT #0 r232730: buildworld broken with CLANG?

I might have missed the point but since a week now I can't build FreeBSD
10.0 CURRENT/amd64 with CLANG anymore.

Amongst other problems I was told that the code this momnet is incapable
to build properly with CLANG, but then several fixes where merged.

Building world ends up everytime at the below shown stage. What's wrong?
If I missed something - please enlighten me.

My src.conf attached.


Regards,

Oliver
