bjs 283ce280f8 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.

NOTE: Unfortunately, JACK wants to use a linux /proc filesystem to
perform shared memory housekeeping tasks. Therefore, if your platform
supports a "Linux-compliant" proc filesystem, we recommend mounting one
prior to using jack. On NetBSD, this can be accomplished with the
following command:
mount_procfs -orw,linux /proc <mount point>
Conventionally, the mount point is /proc. If you wish to use a different
pathname for this filesystem, you may define the JACKD_PROCFS_PATH
variable in your build environment or mk.conf as shown below.
JACKD_PROCFS_PATH= /emul/linux/proc
ATTENTION: NetBSD-current users who wish to run jackd with real-time
scheduling will likely find that the loader fails to mmap
the driver module(s) when using -R. Until this issue is re-
solved, one may work around this problem by using the -m
(--no-mlock) option.
