So that suggests that gutenprint52+usb has an unsatisfied runtime
dependency on libusb (or in other cases it could be another library --
unfortunately, it looks like CUPS isn't capturing that -- but libusb
seems lke the most likely culprit).

I take it libusb isn't a standard component on OS X, so we need some
way to ensure it gets installed (either by static linking if possible,
in which case we'd have to distribute the source, as it's LGPL2.1+, by
bundling, or by otherwise arranging for it to be installed on
Gutenprint installation).
