As noted in #2773, the installation section of the FAQ is out of date, and our installation documentation in general does not give sufficiently clear and correct advice, particularly for OSX and Windows users.
My inclination is to strongly recommend that non-expert OSX and Windows users take advantage of either Enthought or Continuum.io.
My impression is that if they really don't want to do that, then the recommendation is to first install python from python.org, and then for everything else use pip and hope for the best.
