scipy doesn't install with pip

https://travis-ci.org/suavecode/SUAVE/builds/38543833

language: python
python:
  - "2.7"

install:
  - "pip install numpy"
  - "pip install scipy"
  - "pip install matplotlib"
  - "python setup.py install"

# run test
script:  
  - "python automatic_regression.py"

fails at pip install scipy, looks like it's complaining that blas or lapack is missing. would be great if scipy was part of the default site pacakges, ref #2650.

for now, using apt-get python-scipy and the system_site_packages:

language: python
python:
  - "2.7_with_system_site_packages"
before_install:
    - sudo apt-get install -qq python-numpy python-scipy python-matplotlib
install:
    - python setup.py install

Having SciPy preinstalled is covered by #2650.
