the last released was based on a new version of ALSA that many people do
not yet have. this has been fixed in Ardour SVN. For now, go to that
line, and remove the SND_SEQ_PORT_TYPE_SOFTWARE (I have a gut feeling
that you know how to). its just a preprocess symbol that is not defined
in the version of ALSA you have, and I would not recommend upgrading
ALSA unless you have a very good reason to do so.
