This could be a result of your numpy installation being incomplete
(likely do to not being correctly linked to blas/lapack). What happens
when you try:

python -c "import numpy"

on its own? Does it fail with the same error? If so, you need to focus
on numpy. One subtlety to be aware of is that you need to remove the
build directory in your numpy directory whenever you need to rebuild
numpy.

HTH,
