Another great removal of dependencies - thanks Lainey! Please revert the Makefile change, and let's get docker compose working for you.

@laineyhm Github will auto link issues using the # syntax. You need to fix the issue link in the PR description so that the # and number are next to each other, so that the issue is linked correctly.
