simplemessagesystem example1 not compiling

Hi all, this is a newbie question:

I'm trying to comunicate an Arduino Uno with max/msp, and i can't compile de sketch onto the arduino, i'm using arduino 1.0
it says:

SimpleMessageSystem_example_1.cpp: In function 'void loop()':
SimpleMessageSystem_example_1.pde:-1: error: 'messageBuild' was not declared in this scope
SimpleMessageSystem_example_1.pde:-1: error: 'messageGetChar' was not declared in this scope
SimpleMessageSystem_example_1.cpp: In function 'void readpins()':
SimpleMessageSystem_example_1.pde:-1: error: 'messageGetChar' was not declared in this scope
SimpleMessageSystem_example_1.pde:-1: error: 'messageSendChar' was not declared in this scope
SimpleMessageSystem_example_1.pde:-1: error: 'messageSendInt' was not declared in this scope
SimpleMessageSystem_example_1.pde:-1: error: 'messageEnd' was not declared in this scope
SimpleMessageSystem_example_1.pde:-1: error: 'messageSendInt' was not declared in this scope
SimpleMessageSystem_example_1.cpp: In function 'void writepin()':
SimpleMessageSystem_example_1.pde:-1: error: 'messageGetChar' was not declared in this scope
SimpleMessageSystem_example_1.pde:-1: error: 'messageGetInt' was not declared in this scope

any ideas of what's happening?
I got the simplemessagesystem library in libraries, and the sketch shows up in the examples tab.

Thanks in advance to anyone that can help!

At the top of this page: Arduino Playground - SimpleMessageSystem

it says "USE THIS INSTEAD:" Arduino Playground - Messenger

Thanks for your answer!

Yep, and then use cmd messenger instead!
It doesn't compile as well... soi found an max patch example that looked allright with sms so i gave it a try.
But you're right, now back to cmdmessenger...
