RFBee Master (Latest) Sketch Won't Compile

I downloaded the RFBee code from GitHub and ran it on several different windows machines with Arduino 1.0.5 IDE. I have not made any modifications, It won’t compile using the board selection Arduino Pro Mini 3.3v w ATmega168 - I am assuming this is the board type to select. I downloaded several different versions found on the forums and they wouldn’t compile either. Does anyone have any ideas?
