Guys,
I am not a total newcomer to the command line. I have been using the
CLI for about two years. I have been installing, compiling, and using
*nix programs, which have been ported over to OSX's X11. I have had a
linux box (which I build into a server case, so I can take it to gigs)
for about a month. I have found that linux is very similar to OSX
command line, so everything has carried over (and sftp'ed and scp'ed
over) easily.
I am a newcomer to linux audio, though. The cd player works and I can
hear sound in the headphones from the motherboard soundcard. Ardour is
compiled and installed, and many of the other sound programs are
installed and launch fine, but I am snagged by the jack/qjackctl thing.
You can suggest command line stuff. I am sure there are big holes in my
understanding, but I don't think I will accidentally erase my hard drive.
My current status with jack, qjackctl is as follows. If I run 'jackd'
from the command line, I get:
$ jackd -d alsa
jackd 0.102.20

It looks like jack is working. But when I next run 'qjackctl' from the
command line, I get:
$ qjackctl

Also, the qjackctl GUI window launches and displays this message:

Thanks for the help!

I think it would, yet it would of course not get the best out of your
processor so build a kernel from source may be th better way to get the
thing working.
david is a newcomer to linux, isn't confident about what "groups" are,
and you're suggesting to him that he should build his kernel from
source?
david, have you tried running jack from the command line, without
qjackctl?
