Fix pip and Git

[Kwpolska]

1. Fix pip naming (PyPA is the organization behind pip)
2. Fix GIT → Git spelling (that’s the official way to spell it)
3. Install pip using get-pip.py instead of deprecated easy_install

Keep up the good work!

(PS. might be nice to clean up indentation and trailing whitespace in the script)

Shouldn't this be adapted as well?

Ah, the joys of code duplication. Fixed, thanks.

Another thing, when installing Python via brew, does it not come with pip out of the box?

I edited the code that was already there and assumed it was doing things correctly, but yes, brew should install pip. @guarinogabriel, perhaps pip installation should be removed completely and brew install python will take care of things.

@carhartl @Kwpolska – I agree with you. I will merge your PR and I will update the installation commands to use brew install python instead.

Thanks for your contribution!

@carhartl @Kwpolska – Actually, the brew install python command is already there. I will remove the pip installation from the install commands.
