I am trying to set up ActiveMerhcant in my RoR application and using  
the tests that come with the peepcode PDF. I am getting an error when  
I run rake test that I don’t know what to do with, and I am hoping  
someone can give me some guidance.

The application also uses acts\_as\_state\_machine - and I think the  
problem lies there

I googled for Scott B., and I can see he has been a significant  
contributor , but I don’t know how to interpret or resolve this.
