Have you modified the header of the sketch? I only get these errors when the defines are commented out:

#include <avr/wdt.h>

#if defined (__AVR_ATmega328P__) || defined (__AVR_ATmega328__) // Arduino Uno hardware I2C pins
    #define SDA_PORT PORTC
    #define SDA_PIN 4
    #define SCL_PORT PORTC
    #define SCL_PIN 5

#elif defined (__AVR_ATmega1280__) || defined (__AVR_ATmega2560__) // Arduino Mega hardware I2C pins
    #define SDA_PORT PORTD
    #define SDA_PIN 1
    #define SCL_PORT PORTD
    #define SCL_PIN 0

#else // for other boards select I2C-pins here
    #define SDA_PORT PORTC
