> I have just read about Bazaar

There is no need to, because we have moved the source entirely to GitHub.

Strange, I assume you are on Ubuntu Trusty, like me
libjack0 1:0.121.3+20120418git75e3e20b-2.1ubuntu1 is installed.

I can reproduce the issue by installing libjack0

This solves the issue on my system
sudo apt-get install libjack-dev libjack0 portaudio19-dev

It looks like there is a kind of package dead lock with jack 1 and 2
I will file a Bug.
