Thanks for sending the cpuinfo.py output. Comparing it's output
and the numpy/distutils/fcompiler/gnu.py source, it seems that
you are using some older version of numpy. The -march value should
be 'nocona' for your case.

So, try upgrade numpy from svn (or just copy the gnu.py file from
svn to numpy installation directory).
