I noticed that too. I haven't used scons before so I was muddling

Only to the point of opening it and getting its fatal error message  
about there not being a suitable audio device, about which I'm  
advised to complain to Apple or adjust my Jack settings.

We could add a jack-devel port for that version if desired.

Variants for this in the ardour2 port sound reasonable.
