This warnings can be ignored.

To avoid such hooks and all the troubles on 64-bit platforms, 
numpy/distutils/system_info.py needs a 64-bit support
in setting up default_* directory lists. I can write the patch if someone
could provide information how to determine if one is running 64-bit or 
32-bit applications. numpy.distutils.cpuinfo can give is_64bit()->True but
that does not guarantee that used software is 64-bit.

What are the values of


in your system?

What was the output when you run setup.py?
