Ah! THANK YOU!

Ran 481 tests in 1.956s

OK

Now on to doing it again with MKL...
>From the numpy directory:
rm -fr build
cp site_mkl.cfg site.cfg

where site_mkl.cfg is:
-----------------------------------------------------------------------
[DEFAULT]
library_dirs=/opt/intel/mkl/8.1/lib/32
include_dirs=/opt/intel/mkl/8.1/include

python setup.py install >& inst.log

Looks OK, so in another window:
