odkmaker is built on the Ruby Rack server stack, so look up how to run Rack servers, and apply that to config.ru. Phusion Passenger works.
For a quickstart type local dev run, get the shotgun gem, make sure you have all the required stuff, as well as a webserver gem such as mongrel, and then type shotgun config.ru.
