For fun, here is a script 'lilypond-select'; I haven't tried it. Use it with 
'sudo'.

--
#!/bin/bash

# Select MacPorts LilyPond version lilypond or lilypond-devel.


if [ "$1" = "dev" ]
  then
    port deactivate lilypond
    port activate lilypond-devel
elif [ "$1" = "stb" ]
  then
    port deactivate lilypond-devel
    port activate lilypond
else
    echo "lilypond-select  selects MacPorts ."
    echo "Takes one argument, \"dev\" for lilypond-devel, \"stb\" for lilypond."
fi
