I found I could force clang to use libc++ with this line in mk.conf:

CXXFLAGS+= -stdlib=libc++

But unfortunately lang/nodejs still failed to build. Setting clang to use libc++ could allow it to pass the compilation stage. It failed at the linking stage.

It seems clang used the libc++ headers to compile but still looks to link with the system's libstdc++ so it caused the problem.
