I think that returning None would be a better option. The function
documentation says:

  Tries to find 'executable' in the directories listed in 'path'.

  A string listing directories separated by 'os.pathsep'; defaults to
  os.environ['PATH'].  Returns the complete filename or None if not found.

If os.environ['PATH'] is empty the function returns None:

  >>> from distutils.spawn import find_executable
  >>> find_executable('does not exist', path='/bin:/usr/bin') is None
  >>> find_executable('test', path='') is None

This would be consistent with the function definition. If PATH is
undefined, the executable cannot be found, therefor returning None seems
like the right thing to do.
