hi,
i'm not sure if i understand you correctly, but if you are
talking about the alsa tarball and the --with-jack option of
the alsa config: this is not necesary to run jack. the
--with-jack option of alsa applies to building the pcm_jack
plugin, to use alsa native applications as jack clients
(which works only half btw), and does only apply to alsa-lib
