Upgrading Django to use Virtualenv on WebFaction

Recently, I wanted to upgrade my website on ye olde Django 1.6.5 to finally come up to speed with Django 1.8.3 (current, as of this writing). However, I realized that upgrading a WebFaction webapp in situ seemed to be a rather painful process. In addition, WebFaction doesn’t set you up with Virtualenv by default, and I’d like to be able to upgrade Django and the other packages I need for my site without affecting any of my other sites.

I’m going to show how I did my upgrade, but of course, you may have things set up differently, and YMMV. However for a relatively simple site, like mine, I hope this will be helpful.
