Arduino Mamaba Shield Sample Code Error

Using Arduino Networking, Protocols, and Devices
#1

I use sample code on http://cdn.sparkfun.com/datasheets/Dev/Arduino/Shields/mamba_arduino.zip

use this upper example code

but always has this error

i use arduino IDE last version , 0022, 1.0.1

and I tring delete hardware/arduino/core/WInterrupt file too

always show this error

help me plz
