Today, I tried again, after CLANG/LLVM has been updated to version 3.0.
Same error.

This is the addendum I made to the /etc/make.conf:

##
##      CLANG
##
.if defined(USE_CLANG)
.if !defined(CC) || ${CC} == "cc"
CC=clang
.endif
.if !defined(CXX) || ${CXX} == "c++"
CXX=clang++
.endif
# Don't die on warnings
NO_WERROR=
WERROR=
# Don't forget this when using Jails!
NO_FSCHG=
.endif


I think I should file a PR ...
