agreed.. the exception is made for portaudio, because while they have no CVS, theres no 'release' in the past few years. afaik 'Audacity' includes portaudio in their tarballs as well (not sure about CVS, as i hate audacity and just saw this on LAU.)
Portaudio has a CVS. Portmidi doesn't have, as far as i know.
best greetings, Thomas
