pyparsing version parsing error

With the 1.3.0 build from Gohlke's site (http://www.lfd.uci.edu/~gohlke/pythonlibs/), when I try to import matplotlib, I get a pyparsing error.  I have pyparsing 2.0.1 installed.  Here's the error:

    Python 2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)] on win
    32
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import matplotlib
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
      File "C:\Python27\lib\site-packages\matplotlib\__init__.py", line 121, in <mod
    ule>
        '.'.join(str(x) for x in _required)))
    ImportError: matplotlib requires pyparsing >= 1.5.6
