I just bought my Arduino Mega 2560 today and an ethrnet shield. But unfortunately when I tried to compile the same sketch on the mega says:
c:/program files/arduino-1.0.2/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/../../../../avr/lib/avr6/crtm2560.o: In function `__vector_default':
(.vectors+0x8): relocation truncated to fit: R_AVR_13_PCREL against symbol `__vector_2' defined in .text section in c:/program files/arduino-1.0.2/hardware/tools/avr/bin/../lib/gcc/avr/4.3.2/../../../../avr/lib/avr6/crtm2560.o
