In short, you've messed up your jackd installation. I have no idea what
you did to your sources.list or if you compiled jackd manually, but
you're clearly no longer using the jackd1 provided by Debian Wheezy.

Wheezy has version 0.121.3, yours is 0.124.1:


Also, Debian's jackd uses /dev/shm and not /tmp (line 58):


Just clean it all out (uninstall, rm, whatever) and go back to the
pre-packaged jackd.
