Log Message:
Move audio/jack-devel to audio/jack: jack 0.100.0 was broken on many
platforms and a hideous anachronism.  On NetBSD-current/i386 and amd64,
at least, I can say that this package works very well.  If you have issues
with the audio skipping and are running NetBSD 4.99.x, try updating to
rev. 1.241 of sys/dev/audio.c; the changes to audio_poll() and the pause
attribute handling (in large part thanks to help from jakemsr@openbsd.org)
are important for proper functioning of jack (though you may find it
works regardless, depending upon your audio driver, how demanding your
"workload" is, etc.).  I will submit a pullup request for this change
for NetBSD 4 as well.

JACK now supports both our native audio API and OSS--I recommend
trying both.
