Comment(by jeremyhu@…):
Yes, libstdc++ from the host is being used. This is the case with apple-
gcc42 as well, but I see that the gccXX ports use their own libstdc++
I don't like the idea of ports built with gcc46 using
/opt/local/lib/gcc46/libstdc++.6.dylib and ports built with gcc47 using
/opt/local/lib/gcc47/libstdc++.6.dylib ...
1) The gcc-4.2 libsdtc++ doesn't even support c++-03
2) We should make a port for llvm's [http://libcxx.llvm.org libc++] and
[http://libcxxabi.llvm.org libc++ABI] for use by clang
3) gccXX and clang-X.X ports should be updated to use these new ports if
possible.
4) If newer gccXX ports won't work with libc++, we should make a libstdc++
port
