Getting Rails to Work

I am having problems getting rails to work properly in a dreamhost environment. I have followed the instructions in the wiki, without any luck. Dreamhost support told me to post something here because setting up rails is beyond their scope.

Basically, I created a rails app. I can get to the app’s index page, but if I create a new controller, I cannot access it through the web. I have Fast CGI enabled, yet there are no fastcgi processes that I can find (I thought I had to kill them to make code changes take effect.) I am willing to start from scratch if I have to–the app is just a test app. Can someone post or point me to detailed instructions for getting RoR to work properly with a Dreamhost account?
