And I said I was guessing.

Ok.  No clue why.  Take a look at the commit messages; they might
suggest something.  Or they might not.  *shrug*

No clue.  Try reading the source, try running it a few times, try
adding extra "print" commands to the python, try running it again.

I'm not trying to be unhelpful here.  The fact is that GUB is
extremely complicated (almost 20,000 lines of python!), and not really
understood by most people.

A few lilypond developers have tried running GUB, and they all failed.
 I'm the only lilypond developer other than Han-Wen and Jan that's
gotten this to work, and I have spent literally over 100 hours in the
past few months on this task.

Ok.  Then let's stop thinking about changing the repo, and get this to work.

Try doing
  make lilypond
first.  Yes, lilypond-installers should probably depend on building
lilypond, but I'm not at all certain that it does,.

Ok.  If "make lilypond" doesn't work, then try creating this directory manually.

I'm completely serious.  My GUB tree is *filled* with ugly hacks like
this.  It would be nice if they weren't needed, but it'll probably
take 20-50 more hours of work until this is the case.


As I said earlier, GUB is extremely complicated and not for the faint
of heart.  If you're frustrated already, then I honestly think you
should give up now, because it will only get worse from now on.  If
you feel like cursing me and Jan for not fixing obvious problems, then
I also think it would be best if you gave up now, because it will only
get worse from now on.  I wish I could be more encouraging, but I
can't.  I can't even promise that I'll respond promptly to other
problems you have, because there's a lot of jobs I need to do, and
this isn't the most critical.

On the other hand, if you keep careful notes of problems and how to
solve them, and ideally also create patches to fix them, then it'll
help the *next* person who tries to use GUB.

Good luck,
