Comment(by stephen@…):
From what I can gather from this bug, unlike gcc 4.6/7, MacPorts clang
doesn't carry its own standard libraries. It's using the header files and
libraries from the system. It's not an issue with OS X 10.7 since it comes
with compatible headers and libraries. But on 10.6 there's no system
libc++ and its accompanying headers.
For non-C++11 code, it's OK since clang just use the GCC ones. But once
-std=c++0x and -stdlib=libc++ are enabled, it will fail compiling any
files.
Similar issue occurs when trying to build project deployable to 10.6 on
10.7.
