Tried to run docker-osx-dev after a month or so and wasn't able to anymore. Exits right after the Docker Machine test:

…
2016-01-12 13:59:48 [INFO] Complete list of paths to include: 
2016-01-12 13:59:48 [INFO] Starting docker-osx-dev file syncing
2016-01-12 13:59:48 [INFO] Testing if docker machine is running

Machine itself is running, IP matches, Docker Compose is also up.

Docker 1.9.1, VirtualBox 5.0.12.

Is this a dupe/regression of #148 by any chance?
