That's because you use libstdc++ in a C++03 mode and
libc++ (-stdlib=libc++) in a C++11 mode.

1. What's your system? Mac OS X 10.6?

2. Did you install libc++? If not, please install it. See the instruction
"Get it and get involved!" at .

3. If you already installed libc++ but the error happens, then your libc++
is not installed to the standard location. Could you check which directories
are searched by clang (by compiling with "-v" option) and where your libc++
headers are installed?
If you don't want to install libc++ to the standard location,
-LPATH_TO_YOUR_LIBCXX_LIB_DIR as clang's command line options
to specify the location of your libc++.

P.S. -stdlib=libc++ should be added to <linkflags>, too.
