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
##
=2Eif defined(USE_CLANG)
=2Eif !defined(CC) || ${CC} =3D=3D "cc"
CC=3Dclang
=2Eendif
=2Eif !defined(CXX) || ${CXX} =3D=3D "c++"
CXX=3Dclang++
=2Eendif
# Don't die on warnings
NO_WERROR=3D
WERROR=3D
# Don't forget this when using Jails!
NO_FSCHG=3D
=2Eendif
I think I should file a PR ...
