I'm not interested in spending much time trying to make the build actually
work on such a broken setup.  It only worked in CMake < 2.8.10 by an
accident, and wouldn't with universal binary builds.

We can warn about it though.  Try adding something like this to the end
of CMake's Modules/Platform/Darwin.cmake:

if(IS_DIRECTORY "${CMAKE_OSX_SYSROOT}/Library/Frameworks" AND
   IS_SYMLINK "${CMAKE_OSX_SYSROOT}/Library/Frameworks/Frameworks")
  message(WARNING "The SDK Library/Frameworks path
 ${CMAKE_OSX_SYSROOT}/Library/Frameworks
has not been configured correctly on this system.  See
 http://bugs.python.org/issue14018
and consider fixing your symlinks locally.")
endif()

Does it print the warning on your system?
