fixed it myself.

the problem was i wasn't linking against fftw. i had fftw3 installed (via 
fink) and was just assuming dlopen would know how to find it, but nope.

altering the makefile to add -lfftw3 fixed it, using otool -L and 
install_name_tool to point it to the correct binary location.

thanks
