# 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.
