Jan,

Mac OS X should work 100% with avrdude. Your comments are very deep, so 
here's my shallow attempt at a batch file:

avrdude -p m169 -c butterfly -P /dev/cu.USA19QW2b1P1.1 $1 $2

So you just fill in the options, or "-t" for terminal mode. I'm using a 
Keyspan adaptor with (obviously) a butterfly under OS X 10.3.7.
