You could build scipy from source and install it under your home 
directory using (from the root directory of sources):

     python setup.py install --user

This will (on UNIX-like systems) install scipy in 
.local/lib/python2.7/site-packages/scipy. This directory comes before 
/usr/lib/python2.7/dist-packages so no need to tweak the PYTHONPATH.

Then to run the tests, python -c "from scipy import stats; stats.test()".
