Installing SciPy and NumPy using pip

I'm trying to create required libraries in a package I'm distributing. It requires both the SciPy and NumPy libraries. While developing, I installed both using

apt-get install scipy

which installed SciPy 0.9.0 and NumPy 1.5.1, and it worked fine.

I would like to do the same using pip install - in order to be able to specify dependencies in a setup.py of my own package.

The problem is, when I try:

pip install 'numpy==1.5.1'

it works fine.

But then

pip install 'scipy==0.9.0'

fails miserably, with

raise self.notfounderror(self.notfounderror.__doc__)

numpy.distutils.system_info.BlasNotFoundError:

Blas (http://www.netlib.org/blas/) libraries not found.

Directories to search for the libraries can be specified in the

numpy/distutils/site.cfg file (section [blas]) or by setting

the BLAS environment variable.

How do I get it to work?
