I have fixed ruby-mode for emacs but I dont understand how to run the  
interpreter.

I have inf-ruby.el in my ruby-path but what do I need to add to  
my .emacs-file?

Open a ruby file and see what mode you are in then C-h m and C-h b will  
tell you the mode(s) that u have going and the keybindings for them.  
Ruby mode is very handy!
