It depends on the platform. On OS X 10.6, download this library:
and copy it into /usr/lib .
This is a low-level library that takes care of things like typeinfo and exception propagation. Once that is taken care of:
$ clang++ -stdlib=libc++ test.cpp
This will assume that /usr/lib/libc++.dylib exists. And the libc++ headers should be installed at /usr/include/c++/v1/ .
If you need to build libc++.dylib, cd into libcxx/lib and execute ./buildit .
I have no experience on running libc++ on other platforms.
