Having problems compiling the Audio Unit template from Fred Guile's fabulous tutorial at Sample-Hold.com

I did figure out that I had to delete and reimport all the core audio libraries so that they referenced the proper place on my computer.   (I used all the right import settings when dragging them in)

but now I'm getting 37 Apple Mach-O Linker (Id) Errors which I can't seem to eradicate.  They all seem to reference sound oriented symbols like _vDSP_create_fftsetup and _AudioObjectGetPropertyData indicating that I'm missing a framework or something.  I did an hour's worth of googling to no avail.  Any help would be appreciated..

My apologies for what I'm assuming is a noob mistake.
