Python Passenger updated? :crying_cat_face:

I started updating the Python Passenger, and I made good progress. But then I wanted to try it out on my system and my Python is totally and utterly borked. I mean really freaking broken. It explodes.

The steps are quite easy:

1. `brew install python` (or `brew install python3`)
2. You could overwrite system python (maybe this was a mistake)
3. `pip` (or `pip3`) is now available
4. `pip install --upgrade pip` (or `pip3 install --upgrade pip`)
5. Use `pip list` (or `pip3 list`) to list installed pips to decide if they need to be updated or installed

That's basically it. There's also the possibility of using the `--user` flag.

But I can't really try it...

I updated most of the spec suite, just a few pending ones left.

I don't use Python for anything right now. I noticed you do, @bitboxer (for pygments).
If you have time next week, could you look into this? Try it out?
