fix import issues related to ATLAS BLAS

At least on sage.math Sage fails to start up when doing import all. The following doctest failure illustrates the problem:

mabshoff@sage:/tmp/Work-mabshoff/release-cycles-2.9/sage-2.9.alpha7$ ./sage -t  devel/sage-main/sage/numerical/test.py
sage -t  devel/sage-main/sage/numerical/test.py             Traceback (most recent call last):

exit code: 256

The attached patch fixes that, but not in a very clean way. I tried various "clean" approaches, but non of them got past Cython and always lead to link errors.

The patch passes a sage -ba and a testall on OSX 10.5
