Uh, I forgot to mention that I have the following in my ~/.emacs (always 
assuming you also use some Linux or MacOS X; I have no clue about the 
windows configuration):

(setq LilyPond-lilypond-command "Lilypond")

The default should be "lilypond" instead of "Lilypond" - the latter 
links to the current git compilation on my machine.  I'm not sure 
whether it suffices to just say
  (setq LilyPond-lilypond-command "Lilypond <your-options>")
in your Emacs configuration file or if you really have to tweak the 
whole LilyPond-command-alist; but I hope this will give you enough hints.


Actually, thinking about it a little bit more: I recommend you build 
yourself a wrapper like the following for lily s.t. you can call the 
same commands both in Emacs and in the shell.  (This is the essentials 
of my ~/bin/Lilypond shell script; use chmod a+x after writing it. 
Then, the above (setq ...) command does the right thing.)

#!/bin/sh
LILYPOND=$HOME/build/lilypond/release/out/bin/lilypond
LILYPOND_OPTIONS="--relocate"
exec $LILYPOND "$LILYPOND_OPTIONS" "$@"

Here, $@ forwards all command-line arguments to the actual program. 
$LILYPOND should point to your local binary (default: 
/usr/bin/lilypond), and $LILYPOND_OPTIONS should contain all the options 
you want to specify.  "--relocate" is only necessary for out-of-source 
builds, when the default directory for all the Scheme and .ly files is 
not used.


HTH,
