No logic split in here ;-)

The app (BTW it's EdWare
http://meetedison.com/robot-programming-software/) needs audio and if I
understand it correctly, was developed with pyaudio (a python binding to
portaudio) and then enhanced with an alternative binding to the audio
part of pygame.

And since I'm not the maintainer of pyaudio nor pygame, I can't add the
provides information.

So I really want some way to express the logic: "This app needs audio
bindings but they can be provided equally well by two different packages
that are besides from the audio part very different and so don't share
matching provides statements."

Looks like I can't express this in a PKGBUILD.

Thank you
Uwe
