Install PySCeS without Enthought on OSX?

Question

[jolespin]

Is there any way to install PySCeS without installing the commercial Enthought Python Distribution? I'm trying to exclusively use Anaconda's Python distribution and I don't want to clutter my computer with extra distributions.

Uhm.. have you tried installing it just like any other python package -- using pip?

$ pip install pysces
Downloading/unpacking pysces
  Downloading pysces-0.9.1.zip (1.4MB): 1.4MB downloaded
  Running setup.py (path:/home/saulius/.virtualenvs/ms-data/build/pysces/setup.py) egg_info for package pysces

When I tried that, my error started at:

Well, it's pretty self explanatory:

error: extension 'pysces.pitcon.pitcon' has Fortran sources but no Fortran compiler found

You need to install a Fortran compiler before you can compile the package.

I assume you use Mac OS X? HomeBrew package manager is the easiest way to do this.
