The FTL is GPLv2-incompatible, but according to the FSF, it's GPLv3-
compatible... See
http://www.fsf.org/licensing/licenses/index_html#GPLCompatibleLicenses
No blocker here.

Yes, that's the only possible license issue in the future that I can see.
Everything else appears okay...

We don't link anyway.

It appears only in the compiling instructions for FreeBSD. I don't think we
link to it. From the description it seems that dejaview simply makes the FBSD
fonts available to lilypond (at least that's what the CG says).

We don't link, just call.

yes, we just call mf or mf-win

exactly.
> GNU Bison: GPLv3+, but we only call it
The code it puts in the output file (which is linked into lilypond) is GPLv2+
with additional exception to use for any larger work (except other parser
generators).
Cheers,
