Gemini

Gemini was not running because `gemini/Docroot/classes` did not exist on any system that was fresh - since I was running the tests manually before, this folder was always present (which is why the comment line about `mkdir classes` failing was put there and the line below was commented out).

I added the `-p` flag to `mkdir` and now it is always there and does not error out when it already exists.

My first pull request -- how exciting ^_^
