After some investigation, it seems that the real issue is that stderr doesn't get printed during builds, so the message "Don't know how to build portaudio on Windows yet. Sources and build instructions available at: http://www.portaudio.com" is getting lost. Either Windows builds should be fixed, or this should be changed to a panic so that it shows up during cargo build. Thoughts, @mitchmindtree? I'll take a look at getting a build on windows, but it seems like the implementation will either have to depend on a pre-built binary or case on whether MSYS or MSVC is available.
