Comment (by davide.liessi@…):

 Currently LilyPond is approximating the next stable release (2.18).
 It is highly unlikely that they may decide to change their documentation
 building system right now.
 This means that texi2html should be kept in MacPorts at least throughout
 the lifetime of LilyPond 2.18, which probably means more than one year.
