Tracking results of testing

Just keeping track of testing these changes. Made a new mac user and ran. Got this: 

```bash
Error: /usr/local/Cellar is not writable. You should change the
ownership and permissions of /usr/local/Cellar back to your
user account:
  sudo chown -R $(whoami) /usr/local/Cellar
  [ OK ] dependencies installed

  All installed!
```
