Jack sorted, I had jackd2 installed but not jack2, which also installed a libjack-dev (which I guess is the important bit.)

(I see the top one is libxtract so just installed libxtract-dev and will try and work through some more that seem obvious to me for now...)

More errors though:

I don't know why I have to sudo, Sure I used "bzr branch lp:vjpirat"  as mentioned on the launchpad page (accidentally into the folder I had uncompressed from the other version) and everything only has rwxr-xr-x permissions so if I don't I also get this error at the end.
