I’ve recently run into the problem of trying to compile the source for NEURON 7.3a that includes support for parallel NEURON (using MPI) and Python on Mac OS X Lion. Using a number of helpful web resources, I wanted to cobble together an “as-of-this-writing” practice to get a kitchen sink working install for all components.

Because I don’t have the resources to test many version combinations, etc., this assumes OS X 10.7.4 on a Retina MacBook Pro 10,1 (Mid 2012), with a working copy of XCode 4.4.1 installed (available for free from the Mac App Store). I suspect but cannot verify that this will work with many different versions of all of these components. Note: MacPorts is particularly sensitive to very new XCode and OS releases, so right after a new one, things don’t always work right away.

Finally this assumes you have admin access to the computer on which you are installing things and that you will use sudo for good and not evil.

And super-finally, this is basically an aggregate of web sources, some of which I had to modify to get it working. Sources are inline, below. Much is duplicated here because of the transience of web links.
