Thank you, that's exactly what I was looking for wrt. the GUI.

I can luckily skip that part :)
Including instructions to fetch Python 2.6.
(I really wonder why LilyPond nowadays ships with Python 2.6.)

Yes, I'm aware.

This is off-topic, but the idea of a package manager is usually to
compile natively. I'm almost sure that Debian doesn't fetch your
binaries either.

But yes, outside of a package manager it would make sense to take that binary.

Redesigning the GUI for LilyPond is something that would likely
require more effort that I'm personally willing to spend for this. OS
X requires some kind of a GUI when distributing user-friendly apps;
with package managers this can be handled differently.
