I tried compiling modlfo's teensy-braids https://github.com/modlfo/teensy-braids via make command, and am getting the following error

make: *** [AudioStream.o] Error 1

I've defined ARDUINOPATH
Code: 
$ export ARDUINOPATH=/Applications/Arduino.app/Contents/Java

Installed AVR MacPack (which has been renamed CrossPack for AVR), and when trying to select a version of gcc, i get
Code: 
ericneilj:teensy-braids-master ericneilj$ avr-gcc-select 4
avr-gcc-select is not supported any more.
This version of CrossPack for AVR Development comes with gcc 4 only.

Generally can't yet make much sense of this sort of thing, though due to the source code being about 3 years old, could this be an absence of backward compatibility at a certain version? Any help is greatly appreciated.
