setting Gregorian chant.

Replace \bar "||" with \finalis.  I would also use \divisioMinima instead of
\breathe ... but that's just me.

It looks to me like LilyPond is trying to interpret \bar in terms of
gregorian-init.ly, and is failing.  (The diagnostic messages from the
console would be helpful to determine if that's really the case.)  Replacing
\bar "||" with \finalis should delete it.

Yes, there are some difficulties, but you can see a small example of what
the current development version of LilyPond can do at the "Ancient Notation"
section of the GDP site:

Like the rest of the documentation, you can click on the image to see the
LilyPond source that created it.  Some things to note: I did not include any
tweaks because I wanted to see how LilyPond handled unmodified input, so I
would be better informed while working on this section; the output is not
perfect by any means, but it looks much better than the output produced by
the current production version (last time I checked, anyway); there are some
odd collisions (especially the last phrase, which runs into the last finalis
(double bar).

I hope that will be enough to get you started.
