Odd because the error message I get is
ibraries/nunchuck_funcs/nunchuck_funcs.h:13:22: error: WProgram.h: No such file or directory
This means that the nunchuck_funcs.h file is not compatible with the arduion 1.0 IDE is is only compatible with the earlier 0023 version.
Add this to the file in place of the call to include WProgram.h
#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"
#else
#include "WProgram.h"
#endif
