Note that you are using clang installed in your base system instead of the one compiled during buildworld which results in wrong include directories being searched for headers. http://wiki.freebsd.org/BuildingFreeBSDWithClang suggests the following: CC=clang CXX=clang++ CPP=clang-cpp Which should fix your problem. -- Mateusz Guzik <mjguzik gmail.com>
