[pymvpa] Error with import mvpa

[Macare, Christine]

Dear all,

I wanted to import mvpa as indicated in the manual (http://v04.pymvpa.org/PyMVPA-Manual.pdf) and got the following error message: 

IDLE 1.2.4      
>>> import mvpa
Running from numpy source directory.

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import mvpa
  File "C:\Python25\pymvpa-0.4.4\mvpa\__init__.py", line 57, in <module>
    from mvpa.base import externals
  File "C:\Python25\pymvpa-0.4.4\mvpa\base\externals.py", line 17, in <module>
    from mvpa.misc.support import SmartVersion
  File "C:\Python25\pymvpa-0.4.4\mvpa\misc\support.py", line 43, in <module>
    def transformWithBoxcar(data, startpoints, boxlength, offset=0, fx=N.mean):
AttributeError: 'module' object has no attribute 'mean'

I had previously installed: 
Python25 
pymvpa-0.4.4, numpy-1.0.4 and scipy-0.6.0 for Windows. 

I am keen to continue with mvpa and would appreciate any help with this error message.

Thank you in advance.

Christine
