Can't seem to integrate my Docker with new Pycharm 5

Hello everyone,

I'm trying to debug a Django app with PyChar that I have in a Docker container. Originally I only had docker-engine and docker-compose installed, but looking at this post:

https://www.jetbrains.com/pycharm/help/configuring-remote-interpreters-via-docker.html

So I've proceeded to install docker-machine, I can see it working. But when creating the remote virtualenv in Python interpreter settings page, I see no machines in the dropdown.

I've specified my docker-machine executable to be at /usr/local/bin, that's where it is (by the way, Linux Mint 17 here).

Any idea what I'm missing here?

Thanks!
