Not in this case.  Trying to make lilypond-book look at python 3
instead of the packaged python 2.4 requires manually editing
installed files that nobody should ever edit.

There's no problem with having python 3.x installed globally; the
lilypond-book that comes in GUB should look at the python 2.4 we
distribute by default.
