  So far so good.

  How about:

import sys
try:
    sys.version_info
except AttributeError:
    import macpath
    macpath = mac_normpath

  Simple, and doesn't require any platform tests.  (sys.version_info
is new starting in version 1.6.)

  This solution fixes all callers of macpath.normpath without
additional magic.  Keep It Simple.  ;)
