I was installing scipy on my old mac running python 2.7 but had a real hard time installing scipy. I successfully installed numpy without any problems. However installing scipy on both ways using mac ports, pip and compiling from scipy source throwing this error
error: library dfftpack has Fortran sources but no Fortran compiler found
I tried to install fortran compiler
pip install gfortran
port install gfortran
easy_install gfortran
but none worked :(.
To fix this issue i had to install the mac osx installer from this website

Once you do this, scipy will install without any issues. Good luck!!!
