Don't get me started about Ubuntu and jack support. It really is a second class citizen - As it stands jack is not an officially supported package (It's in Universe in Ubuntu speak)... Which means that if you want jack support for any supported application you need to compile it yourself. I think a big part of this is ignorance on the part of the packagers. I imagine that other distros are similar. Part of the problem is that Jack still takes considerable leg work to get up and running properly. It's value may not be apparent to a new user and it is different to how things are done on other platforms. Guaging from places like the Ubuntu Forums and even things like Linux Audio Podcasts only a small subset of users actually get a functional jackd setup working. I am not sure how but it seems to me that the shortest path should be shortened.
