During linking some symbols are not found, they are related to jack, but audacity shouldn't even have a dependency on jack. I have confirmed that this is not an --as-needed issue.

Eh; maybe it shouldn't use the bundled portaudio in the first place.
Audacity has not support external portaudio src yet. I cannot reproduce this issue. What version of jack-audio-connection-kit do you use?
I had jackd 0.105.1 (svn) installed, i reverted to 0.103.0 and it seems to work now, will poke again if the next jack release still causes a problem.
Bug was reported with version that's not even in tree, comment #3. And it works for reporter now.
