Installing Python via MacPorts on Mac.

The following page has instructions for setting up a Python distribution for Astronomy using the MacPorts package manager on Mac:

MacPorts has several advantages over other installation methods, including:

  • No Licensing issues
  • Dependencies are taken care of automatically
  • Easy to update packages 
  • Installs complex packages including numpy/scipy/matplotlib/pyqt4/pygtk 
  • Easy to install several versions of Python (great for experimenting with Python 3)   
The only downside is the initial installation time for some of the complex packages, as these are installed from source (best to start the initial installation of packages overnight). Feedback is welcome!
