I don't know of any tutorial, but you can download the stuff and extract the /opt/piratebox directory. You will need all the dependencies (lighttpd, hostapd, etc.) and you'll have to get them to start by themselves with the correct config files (located at /opt/piratebox/conf)... I think it's possible if you are willing to put some work in it, and if you're familiar with raspbian ;-)
Good Luck!
