Jason,

Not sure if this helps, but make sure you connect using the correct cable
from USBTinyISP and that the cable is also assembled correctly (check the
page on the assembly page for the USBTiny; could be incorrect with respect
to cable and plugs) and that the cable is in the proper header in the
(reprap/makerbot) board. You should then also put in the jumper (provide
voltage to the board). Aso check if the board is soldered correctle (diodes
oriented ok, chips ok?) and the green LED turns on.

To test if the USBTiny works and you can communicate with the board, you can
use the "avrdude -c usbtiny -p m644p" command (also try to run it as root on
your mac) and check if the avrdude responds with something else then "rc
-1". Maybe the output you get also provides some info on what goes wrong ...
