Docker Compose install error - docs or me failing?

Originally posted at https://discuss.redash.io/t/docker-compose-install-error-docs-or-me-failing/262, but perhaps I should have come straight here as it looks like a bug:

Hi all, I'm following the Docker Compose section at http://docs.redash.io/en/latest/setup.html1. Sadly, I fail at step 5:

(default)  ~/src/git/redash/setup/ubuntu_docker/files [master|]

Any clues? Ubuntu Xenial, Docker 1.12.3.

I have some documentation patches ready to submit, but first I'd like to get a working install.

Have you seen my reply on your forum post?

Hey, no I didn't see that, and I still don't see it. Strange - can you check it's there?

apparently I didn't hit the "publish" button... luckily Discourse save drafts :)

I hope PR #1380 will be useful in this matter, can you merge? :)
