I think he is referring to the version of qjackctl which in fact on 
squeeze is 0.3.6.

Forrest: to see the version of jack (not the QJackControl gui) try the 
following command in a terminal:

jackd --version

You can also do this within Pd itself, by making sure you select Media 
-> Jack Here you can also set the input and output channels, maybe start 
with something like 2 to begin with.
As IOhannes suggested do make sure jack is running *before* you start pd.
