I can't start Jack. I tried compiling jack 0.102, and it wouldn't, but I'm
getting the following output from jack when attempting to start
it.10:36:32.209 Patchbay deactivated.

I've noticed that jackd seems to be 0.102, but I've just run a make clean,
reinstalled jackd (via apt) and it's still the same version. I'm running
ubuntu 6.09. Any ideas?
