Nice!

I never tried building it on macosx. From
/usr/include/architecture/ppc/math.h:

/*
 * N.B. When using the C99 "float" entry points that follow, an
 * additional flag must be added to the link step that produces
 * the executable binary -- specify "-lmx".
 */

It seems calling configure with LDFLAGS=-lmx does the trick.

Also the file woodblock.aiff is not quite plug and play. So you
might need something like:

mkdir -p /usr/share/sounds/aubio
cp sounds/woodblock.aiff /usr/share/sounds/aubio

These should be fixed with for the next release.

Thanks for trying, let us know how it goes! 

Bye, Paul
