In this case it might have been better to build jack itself from source and then tell pd to link it instead. I believe there is a configure option for this, IOhannes will know for sure.
I'm willing to try this :)
there's basically two options. none of them includes any special flags to compile Pd.
first i'd probably restore the old jack configuration, so you can have audio again.
#1 rebuild the (proper, working) libjack packages with debugging symbols. there's a description how to build your package with debug symbols if you cannot obtain them otherwise on [1] (in retrospect, this would have been the better choice). this will create a number of packages, you only need to install the newly created libjack-jackd2-0 (which ought to have the exact same version as the original package).
Cool, thanks for holding my hand.
I think the rebuilding with debug symbols was successful.
