For those who don't want to dig into the issues and pull requests, it 
seems that multiple libraries were patching different parts of distutils 
and adding extra quotes to the command line. This was apparently only 
occurring with Python 3.5.

The main reason I want to add to this post is that *Python 3.5 is still 
taking bugfixes*. If there is a problem in distutils, please report it 
to bugs.python.org first so we can fix it, and then look into 
monkeypatching the older versions.

Cheers,
