Do you actually need libshout-idjc? It's now only required for AAC or MP2 streams (with the latest development version.)
Why are you trying to install pulseaudio-module-jack? The official instructions do not say to install that. And I noticed calf-plugins also, again that is not mentioned in the official instructions.

However, when I run IDJC now I just get 'something bad happened' after selecting a profile. Re-installing libshout-idjc and I was able to get IDJC working again. (EDIT: I checked in a basic Debian...
