SPI on the arduino Due

Hey,

I am trying to port a library across from the UNO to my due but I get these errors;

Error compiling.

I guessing they are UNO registers that the DUE doesnt have but I dont know where to start to get to a point where I can fix them.

There is an update of the library to avoid this.
