Ah - no - I only pointed that out in case it was obvious how to read
the recipe there.

Here's the relevant bits:

"""
- sudo installer -pkg archives/gfortran-4.2.3.pkg -target /
- pip install cython
- pip install numpy==$NUMPY_VERSION
- cd scipy
- export CC=clang
- export CXX=clang++
"""

which mean, respectively:

* Install gfortran 4.2.3 dual arch build from pkg installer (in fact
archived at https://github.com/MacPython/scipy-wheels/blob/master/archives/gfortran-4.2.3.pkg
for posterity and this repo);

* pip install cython numpy
* cd scipy
* export CC=clang
* export CXX=clang++
* python setup.py install   # or whatever local install method you like

The repo just assures us that that this still works, and builds our
wheels for us when we release...

Cheers,

Matthew
