I\'m having serious difficulty installing Scipy with pip on Mountain Lion. I\'ve tried:
sudo pip install -e git+https://github.com/scipy/scipy#egg=scipy-dev
I recently also had trouble getting scipy to install on a virtualenv. My problem was that gfortran was not seen properly. I used macports sudo port install gcc48
and created a symlink to just gfortran by:
sudo ln -s /opt/local/bin/gfortran-mp-4.8 /opt/local/bin/gfortran
After that, pip install scipy
worked without any errors on my virtualenv.
