           Summary: cannot build ctypes module from Python
           Product: clang
           Version: 2.8
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P
         Component: Static Analyzer
        AssignedTo: kremenek at apple.com

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::
