This is not jackd2 as provided by Debian in the current stable release. Please
install 1.9.10+20150825git1ed50c92~dfsg-5 and try again.

libreadline6 was replaced by libreadline7 in stable. The issue is that the
version of jackd2 you've installed is not compatible with stable.

In fact, the entire reason I'm using Debian right now is because this sort of thing is actively prevented by Debian's package maintenance process. I've been resisting the urge to channel the spirit of Torvalds into this email :P
