Hey Kyle

I'm using Hans-Christoph's Pd-0.39.2 extended test 3, which is
compiled with jack support - I don't think the binary on Miller's site
is, although I'm pretty consistently wrong about many things.

here's the link to hc's installers page:
http://at.or.at/hans/pd/installers.html

I don't think I've done any fancy configuration in jack itself - just
set the buffer size nice and low and make sure jack is selected in the
media menu.  Seems to work beautifully, and gosh 0.39 is fantastic.

Good luck!

cheers
