[Facebooker-talk] link_to issue when running outside of web server

[Mike Mangino]

There is a lot of magic required to make those helpers work. You will  
probably need to include the facebooker helpers. The Publisher code  
sets up a class with all of the helpers available, you might try  
looking at that.
