on python27 64 bit
import platform
print platform.machine()
i386
print platform.architecture()
('64bit', '')
sys.maxint
9223372036854775807

on python2.6 32bit
>>> import platform
>>> print platform.machine()
i386
>>> print platform.architecture()
('32bit', '')
sys.maxint
2147483647

And given David's answers if python is 64(or 32) then numpy/scipy is
the same or not working :-)

Thanks
Vincent
