Just out of curiosity, I managed to compile the binding and successfully
run the examples.

You are correct to state that the build system is flawed, and needs some
steps to compile correctly. Here is what I did:

1) Get the latest ProteaAudio and also the RtAudio code from
http://www.music.mcgill.ca/~gary/rtaudio/release/rtaudio-4.0.7.tar.gz

2) Update the RtAudio code in ProteaAudio:

$ cp -r rtaudio-4.0.7/RtAudio.* rtaudio-4.0.7/RtError.h
rtaudio-4.0.7/include proteaAudio_src_090204/rtaudio

3) Modify the ProteaAudio makefile to suit your needs
4) $ make
5) $ make lua
6) Copy the resulting proAudioRt.so somewhere in your LUA_CPATH
7) ???
8) Profit :)

The diff of necessary changes in step 3 is in the attachment, modify the
path to suit your installation of Lua (this works on Ubuntu).
