>Description:
By default, "audio/audacious-plugins" enables the option for "jack",
causing "audio/jack" and its dependencies (notably "databases/db4")
to be built.

In my preferred set of packages, "audio/audacious-plugins" is the only
package to require "jack", so I'd rather disable it.

Setting "PKG_DEFAULT_OPTIONS+=-jack" and rebuilding "audacious-plugins"
fails packaging with:

[...]
=> Automatic manual page handling
pkg_create: can't stat `/tmp/pkgsrc/audio/audacious-plugins/work/.destdir/usr/pkg/lib/audacious/Effect/resample.so'
pkg_create: can't stat `/tmp/pkgsrc/audio/audacious-plugins/work/.destdir/usr/pkg/lib/audacious/Effect/speed-pitch.so'
=> Creating binary package /tmp/pkgsrc/audio/audacious-plugins/work/.packages/audacious-plugins-3.5.2nb14.tgz
pkg_create: can't stat `/tmp/pkgsrc/audio/audacious-plugins/work/.destdir/usr/pkg/lib/audacious/Effect/resample.so'
pkg_create: can't stat `/tmp/pkgsrc/audio/audacious-plugins/work/.destdir/usr/pkg/lib/audacious/Effect/speed-pitch.so'
pkg_create: lstat failed for file lib/audacious/Effect/resample.so: No such file or directory
[...]

Investigation thus far shows that they are omitted from the list of
effects plugins when "--disable-jack" is used ("-jack" in PKG_OPTIONS).

So far, I have not figured out why disabling "jack" support causes
these libraries to be omitted.
>How-To-Repeat:
Set "PKG_DEFAULT_OPTIONS+=-jack" or "PKG_OPTIONS.audacious-plugins+=-jack"
and attempt to "make package" or other operation which creates a binary
package of "audacious-plugins".
