You cannot have both active indeed, but you can install them both (one active, 
one inactive). The recipe to end up with stable, but have current development 
version at hand for activation:

sudo port install lilypond-devel
sudo port deactivate lilypond-devel
sudo port install lilypond

then when you want to try develop:
sudo port deactivate lilypond
sudo port activate lilypond-devel

and the other way around to switch back to stable:
sudo port deactivate lilypond-devel
sudo port activate lilypond

only the active one will be upgraded with a sudo port upgrade outdated (over 
time you can even have multiple historical versions side by side at hand for 
activation by specifying the explicit version)
