[ase-users] namespace collision in io module with Python 2.7

[Nichols A. Romero]

I have Python 2.7 and the SVN version of ASE & GPAW. I think this is a namespace
collision between the io module in ASE and the io module in Python 2.7.

[naromero:~/gpaw_custom_hdf5/gpaw/test] naromero% python2.7 ./test.py
Traceback (most recent call last):
  File "./test.py", line 11, in <module>
    import gpaw.mpi as mpi
  File "/Users/naromero/gpaw_custom_hdf5/gpaw/__init__.py", line 211, in <module>
    from gpaw.aseinterface import GPAW
  File "/Users/naromero/gpaw_custom_hdf5/gpaw/aseinterface.py", line 9, in <module>
    from ase.units import Bohr, Hartree
  File "/Users/naromero/ase/ase/__init__.py", line 16, in <module>
    from ase.io import read, write
  File "/Users/naromero/ase/ase/io/__init__.py", line 5, in <module>
    from zipfile import is_zipfile
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/zipfile.py", line 462, in <module>
    class ZipExtFile(io.BufferedIOBase):
AttributeError: 'module' object has no attribute 'BufferedIOBase'

Is there an easy fix for this?
