clang in MacPorts has problems with "libc++" — at Initial Version

Description
clang++ compilers (any version) installed with MacPorts have problems when C++11 are being used. That's because the C++11 can not be found.
I attached a simple C++ source file with 3 lines of code. It can not be compiled with an MacPort installation of any clang compiler. Try
clang++ main.cc
#fails because one header is c++11 specific
clang++ -std=c++11 main.cc
#fails because <type_traits> can not be found
clang++ -std=c++11 -stdlib=libc++ main.cc
#fails because <complex> can not be found
Please understand, a clang++ installation that can not be used with C++11 is pretty useless.
The problem was discussed on the clang developer mailing list: http://lists.cs.uiuc.edu/pipermail/cfe-dev/2012-August/023867.html
Douglas Gregor <dgregor@…> says: "MacPorts needs to start installing libc++ headers relative to the clang binaries it installs; they can look at where those headers land in an Xcode-installed Clang."
