Sounds good, jack is up and running (at least it is not complaining :-)

Well, open another terminal and execute pd from there. Jack "uses" the
terminal until you stop it (with <ctrl>-c).

Do you have it installed? ("rpm -q qjackctl" to see if it is there). If
it is installed be careful, the last character is the letter "l", not
the number "1" (as in the command line you copied).

The modules seem to be fine to my eyes...
