I'm following Chapter 2 of Elliot Williams' book Make: AVR Programming. I'm on an iMac.
I get a success message in Terminal when I input:
avrdude -p m328 -c usbasp -v -B 10
So, I know that my programmer and micro controller are working.
(If I don't set the Bitclock to 10 then it throws an error.)
My problem is working with the Make file. When I try "make flash" I get an error message.

avrdude done. Thank you.
make: *** [flash] Error 1
I think that the problem is that the Bitclock isn't set in the Make file, and I'm not sure how to do so. (If I have some other error, please let me know. I'm guessing.) The Make file can be found on gitHub at: blinkLED Make File
I have set the MCU = atmega328 (which is the micro controller that I'm using.)
