I got a few emails from Pieter about packaging faado (Free from 64Studio
and myself were copied). Does not look too easy - various issues. I have
not yet started work on this, it would be great if you could get in
touch with them (more below).

Why install to /usr/local? Is this temporary while you experiment?

You need (at least) to rebuild jackd with support for faado (ie: package
faado and then include the development package as a build requirement
for jack-audio-connection-kit) - stock jack only supports freebob. Or do
a jack test build/install in the machine in which you have the faado
libraries installed. Stock jack packages do not include faado support. 

It may be better to package svn jack. I don't actually remember the
state of faado support in the latest "stable" release (which has known
problems and is not actually "stable" :-). Current svn is supposed to be
better behaved than 0.109.x (current "stable") and that is what I'm
testing in Planet CCRMA right now and running in my laptop. The Planet
CCRMA jack package is also better tuned for the realtime kernels I
support.

I'm forwarding you the thread from Pieter in a separate email...
Best.
