I can tell more. I have tried Audacity + PortAudio (v19) + JACK, all from current CVS, without any success. Developers have suggested me to join to development process and play with source code :-) It was few months ago. Current state is the same. I think, Audacity and PortAudio teams take in mind MS Windows users as main projects target, rather Linux users. OTOH, currently, I think, it is not interesting to use any audio software in Linux without JACK support.
