Issues with installation of pduino Firmata for Arduino and Pure Data interface

Hey guys

I'm rather new to Arduino and Pure Data and I am having trouble trying to install the firmware for Arduino to read the Firmata examples. I am on Mac OSX and I am using a Arduino Uno. I have updated the 'Firmata' folder in the libraries folder of my Arduino package contents but when I attempt to verify or upload a Firmata (SimpleAnalogFirmata) sketch to the Arduino it comes up with the attached error message.

This probably a pretty simple issue but if anyone can provide some help with this issue I would be very, very grateful!

Thanks in advance :),
