I'm pretty certain you're mistaken here:

    >>> import doctest
    >>> def test1():
    ...     """
    ...         >>> '   ' # doctest: +NORMALIZE_WHITESPACE
    ...         ' '
    ...     """
    ... 
    >>> doctest.testmod()
    (0, 1)

The test passes.  What wouldn't work, though, is if you tried to match
whitespace that is not expressed as whitespace in your test, e.g. tabs:

    >>> def test2():
    ...     r"""
    ...         >>> '\t\t ' # doctest: +NORMALIZE_WHITESPACE
    ...         '\t'
    ...     """
    ... 
    >>> doctest.testmod()
    **********************************************************************
    File "/home/mg/.python", line 25, in __main__.test2
    Failed example:
        '\t\t' # doctest: +NORMALIZE_WHITESPACE
    Expected:
        '\t'
    Got:
        '\t\t'
    **********************************************************************
    1 items had failures:
       1 of   1 in __main__.test2
    ***Test Failed*** 1 failures.
    *** DocTestRunner.merge: '__main__.test1' in both testers; summing outcomes.
    *** DocTestRunner.merge: '__main__' in both testers; summing outcomes.
