This appears to be a regression because I do not get the error with 
Python 3.1.1.
I rebuilt Python3.1.1 and Python3.1.2 to compare the builds (I don't 
know how to keep the two Python 3.1 minor releases separate). From the 
diff it is clear that Python3.1.2 (build directory) is adding the .io 
but the Python3.1.1 (build311 directory).

$ diff build/py3k/numpy/lib/utils.py build311/py3k/numpy/lib/utils.py
