Problem Uploading: Mac OSX 10.9.1 and Duemilanove AT MEGA 328

Hello,

I am new to using an arduino board and am having some issues getting started. I have searched and searched but cannot seem to find a resolution to this issue.

Mac OSX 10.9.1
Duemilanove ATmega328 (it is actually a Robo1 that comes in the starter kit, but the manual states to select the Duemilanove)

I installed the IDE without issues, and am able to run the arduino application.
I selected the correct board under "Tools".
I selected the serial port that most closely resembles the one described in the manual... "/dev/tty.usbserial-A603HK81"
I opened the example "Blink" and clicked "upload"

This returns an error message stating: "avrdude: stk500_recv(): programmer is not responding"

I don't know what this means... obviously there is some issue with the computer and the board communicating, but I don't know what it is. I have attempted to find a thread that describes this issue, but the only ones I have found do not seem to have any answers for me.

Any help would be appreciated!

Thanks in advance.

Do the Receive and Transmit LEDs on the Arduino blink when you upload? If the Receive LED blinks at least you know you have the right serial port.
