Re: tetex 2.5 and lilypond 2.0

[Mats Bengtsson]

The changes necessary to make lily 2.0 compatible with
teTeX 3.0 should be very simple. From the top of my
head, make a new directory /usr/share/lilypond/fonts/map/
(or wherever your .../lilypond/fonts/ currently is installed)
and put a copy of the file lilypond.map in that directory.

On a Debian compatible installation, I recall that the
LilyPond TeX related files are included into the standard
teTeX texmf directory structure, so in that case, there is
probably already a fonts/map/ directory where you can
place the lilypond.map file. Then, you should also run
texhash (as root) to update the filename database.

If your LilyPond binary is compiled using an older teTeX
you might also get compatibility problems with the version
of the kpathsea library which is linked. However, if you
compile LilyPond yourself on a machine with teTeX 3.0,
that shouldn't be a problem.
