        # On OS X, binary installers support extension module building on
        # various levels of the operating system with differing Xcode
        # configurations.  This requires customization of some of the
        # compiler configuration directives to suit the environment on
        # the installed machine.  Some of these customizations may require
        # running external programs and, so, are deferred until needed by
        # the first extension module build.  With Python 3.3, only
        # the Distutils version of sysconfig is used for extension module
        # builds, which happens earlier in the Distutils tests.  This may
        # cause the following tests to fail since no tests have caused
        # the global version of sysconfig to call the customization yet.
        # The solution for now is to simply skip this test in this case.
        # The longer-term solution is to only have one version of sysconfig.
