New description:
Apparently Numpy forgot about the existence of "x86_64" systems:
{{{
Python 2.7.2 (default, Feb 3 2012, 15:29:15)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from distutils.util import get_platform
>>> get_platform()
'macosx-10.6-x86_64'
}}}
The bug is in `src/numpy/distutils/system_info.py`:
{{{
if sys.platform=='darwin' and not os.environ.get('ATLAS',None):
args = []
link_args = []
if get_platform()[-4:] == 'i386':
intel = 1
else:
intel = 0
if
os.path.exists('/System/Library/Frameworks/Accelerate.framework/'):
if intel:
args.extend(['-msse3'])
else:
args.extend(['-faltivec'])
link_args.extend(['-Wl,-framework','-Wl,Accelerate'])
}}}
The above code is actually wrong in so many different ways that it should
better be scrapped altogether. However, I'm going for a minimal fix in
this ticket, adding a check for "x86_64". Let's also see what upstream
says.
