[AstroPy] Deployment and packaging

[Brad Holden]

The MacOSX version of scisoft is independent of the ESO one.  
For example, it has 1.5.1 of numpy.

That said, it does bring another 700 Mb of stuff with it that you may not want.
(It is how I install IRAF, so that part I do not mind.)

I didn't like using Scisoft, however, because it installs multiple copies of some applications I've already installed (like iraf/pyraf).  Plus, I'm not sure all the distributions are up to date.
