Well, myself: The answer is to be found in line 20 -21 of convert-ly, 
further down in the other python scripts. The hard-coded version number 
was not updated from 2.15.2 to 2.15.3 :-)

There is no problem having the installation of lilypond-dev versions in 
/usr/local/. I have the latest FontForge versions there too. Frescobaldi 
finds it all right. I don't run LilyPond as root, only installs it. FWIW 
my first such installation was from SVN sources, not git, and long 
before there was any lily-git.tcl script.

Being a 68-year-old amateur choir singer still working full-time, 
neither a programmer nor a musician, I regrettably must abstain from 
other titles than Bug-stumbler... :)
