If you want to contribute and can build LilyPond yourself, there's no
need to install that development version; you can run it from the
build tree.

I use the (uhm) "attached" scripts to configure and select to use the
lilypond from the local build tree:

   $ clily && make
   $ . here-lily

We could mention this in the developer corner or in a HACKING file?

Jan.


clily:
#!/bin/bash

[ -x configure ] || ./autogen.sh --noconf
rm -f config.cache
./configure --prefix=$(pwd) --infodir=$(pwd)/share/info --disable-optimising 
--enable-gui "$@"


here-lily:
# source me

export PATH=$(pwd)/lily/out:$(pwd)/scripts/out:$PATH

unset LILYPONDPREFIX
unset TEXMF

# ugh: must fool-proof other TeX environment variables
TEXINPUTS=:
MFINPUTS=:
TFMFONTS=:

datadir=$(pwd)/share/lilypond
export TEXMF="{$datadir,"`kpsexpand  \\$TEXMF`"}"

export 
GS_FONTPATH="$datadir/fonts/type1:/usr/share/texmf/fonts/type1/bluesky/cm:/usr/share/texmf/fonts/type1/public/ec-fonts-mftraced"
export GS_LIB="$datadir/ps:$GS_FONTPATH"
