gtklick not starting becaus klick takes too long (jack problem)

[tourette]

Hi!

packages gtklick/klick seem to have wrong/missing dependencies in repos:

I installed gtklick Metronome via Software Center on a pretty fresh 12.04 install.
When I start it, it takes some seconds and then reports: "gtklick Fehler: Zeitüberschreitung beim Starten von klick" (~ "Error, takes too long to start klick").

When I try to start klick in Terminal, this happens:

tworette@nn205ubu:~$ klick -s 3 -i
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
exec of JACK server (command = "/usr/bin/jackd") failed: No such file or directory
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
Cannot connect to server socket err = No such file or directory
Cannot connect to server socket
jack server is not running or cannot be started
can't connect to jack server
tworette@nn205ubu:~$

I tried to install packaage "jackd" with Synaptic, but it didn't help (now, after uninstalling that again, klick in terminal simply says: "can't connect to jack server").
