           Product: clang
           Version: 2.8
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal

As of LLVM 2.8, clang can no longer build the ctypes module from Python (this
has been verified as an issue for Python 2.7, 3.1, and the in-development 3.2).
There were no issues with LLVM 2.7. The relevant Python bug is
http://bugs.python.org/issue10238 (although there is currently nothing
enlightening there).

The error output is::
