Ben -
I modified your makefile a bit to give more warnings (-Wall and -pedantic to
each build statement) and this is what I get:
bash-3.2$ make

There looks to be a fair amount of warnings dealing with the pointers and
types, I'll start looking through these. Hopefully it's a simple type error
hidden in there somewhere that's blocking it from working properly.
