Cannot launch Arduino IDE

Hi Everyone, I just got my first Arduino Duemillanove today! I downloaded IDE 16, installed the USB drivers, and tried to launch the IDE on my brand new MacBook Pro running Mac OS X Leopard.

I got this error: "Cannot launch Java applicaion" Uncaught exception in main method: java.lang.UnsatisfiedLinkError: /Applications/arduino-0016/Arduino 16.app/Contents/Resources/Java/librxtxSerial.jnilib: no suitable image found. Did find: /Applications/arduino-0016/Arduino 16.app/Contents/Resources/Java/librxtxSerial.jnilib: no matching architecture in universal wrapper.

What do i do?!?!

Thanks, Eric
