ok, I got pd running quite normally with Jack ; the only problem are some Audio
I/O errors, that correspond to some clicks 

I discovered that these errors occur when I interact with something else than
the running Pd patch : for example, typing this mail with the keyboard, moving
graphic windows with the mouse, etc, while pd is computing audio. Inside a
patcher window, there are no problems (with the exception to using some graphic
objects like [array]) 
So maybe it's "normal" (or should I get rid off the Gnome GUI ? a lighter
interface like the Blackbox could be better I think)

I start jack using the Qjackctl interface ; (of course) changing the buffer
sizes of the sound card (Hammerfall) has no effect here

here is a sample of these errors :
