I'm wondering if this could be a clang issue in 4.1. The ctypes code is pretty old and hairy and could be triggering a compiler bug that's fixed in 4.2. The ctype patch is just one line adding %p/lib to the library search path so that it can find fink-installed libraries. There's no way that could cause the test failures you're seeing. Ooh, I think I know what's wrong. In python27, I have a patch, in the very last chunk of python27.patch, that makes _ctypes/_ctypes_test.c be compiled with -O0 because anything else triggered a compiler bug in clang which caused test failures. python26 lacks that patch. The bug must have been fixed in Xcode 4.2 so I'm not seeing it. That patch should be added to python26.patch.
