At the moment it is not possible to execute

  python system_info.py

until scipy_distutils is installed first. The reason is that system_info 
tries to compile an extension module to determine the version of ATLAS, 
but do to that, it needs scipy_distutils. One option would be to disable
ATLAS version detection if scipy_distutils is not installed, but then 
again the output of `python system_info.py` would not reflect the real 
state of the system. So, install scipy_core first (or put it's location 
to PYTHONPATH) and then run system_info.py.

Yes, you can ignore it. It's solely an issue of testing hooks and will be 
fixed as soon as I get a moment for it.
