max31855 thermocouple amplifier error

I'm trying to get a modified version of the solder reflow oven from the Ben Heck show up and running. I'm having some problems though. When verifying the code, I get the following errors:

 solder_reflow:189: error: 'MAX31855' does not name a type
solder_reflow.cpp: In function 'void loop()':
solder_reflow:248: error: 'thermocouple' was not declared in this scope

I'm not really sure where to go from here to fix this. Any advice?

I figured it out. I had downloaded the max31855 library from adafruit. Opening up the .h and .cpp files in xcode revealed it was referencing the amplifier starting with adafruit_. Removing this part made my code work.
