Connecting Ultrasonic to Arduino library installation problem

I followed the directions but am unable to compile the sketch.
I am connecting to Arduino Mega 2560.
But it won’t compile and gives me an error message.
Ultrasonic.cpp:167: error: ‘VersalinoBUS’ does not name a type

Based on that error message I would say that you did not copy over all of the files for the library. Be sure to copy the entire library directory, and let me know if the error persists.
