OK, now I see, sorry for the confusion... this seems indeed great, and
automatically invalids everything I have said about the (non)
opportunity of creating different denemo packages.

Still, when you wrote it is possible to "build it with jack enabled, but
avoid it default to using it", did you mean that denemo compiled with
jack (MIDI output) running in a system with no jack (not even libraries)
will work if the runtime options are set accordingly?

Finally: apart from possibly changing the default, may I suggest
replacing "use JACK [default=no]" with something slightly more
explicative (such as "use JACK MIDI ouptut") in the configure script?
