What's the problem? It looks as if jack has started just fine.. I'm willing
to guess that no client can connect to it, am I right?

Judging from the command line for jackd, you've build jack by yourself and
installed in /usr/local instead of /usr/ (where the ubuntu/debian package
has installed jack).

This means that you have two versions of jack installed. This causes huge
problems. I suggest you "make uninstall" what you build, and rebuild it
using ./configure --prefix=/usr (followed by whatever options you've chosen
to use).
