[Denemo-devel] lilypond version weirdness

[Bric]

I have two working lilypond versions installed on my Ubuntu Maverick, 
simultaneously:  2.16.1  and 2.17.7

denemo's config has been using the older 2.16.1 version, or so it 
seems.  When I export as lilypond the *.ly file has:

\version "2.16"

I finally got around to trying to suppress or remove version 2.16.1 and 
make 2.17.7 the default everywhere.

But here's the weird thing:  denemo keeps generating *.ly files with the 
line "version 2.16" in them.

Is this some bizarre coincidence? Is the current git 1.0.9 have a 
built-in "minimum lilypond version compatibility", and it happens to be 
2.16, or is denemo somehow aware of my particular system's lilypond version?

(The additional weirdness is that I am failing to find the proper way to 
remove my lilypond 2.16.1, because I can't find my source tree for that 
version; i think I used a shell script to build it (this was a while 
ago!) and it got installed in my $HOME/bin, but that's a different 
story. When I remove "$PATH/bin" from my path, the "lilypond" command 
starts to mean /usr/local/bin/lilypond, which is 2.17.7, otherwise, it's 
2.16.1. I have launched denemo from the command line, from a shell where 
"lilypond" means /usr/local/bin/lilypond[_2.17.7], and with ~/bin 
missing/moved. Denemo still generates 2.16 *.ly files !)

Any ideas?
