There is no dependency problem I am aware of in that I have always had to build the osalp library by hand. We have looked into using libao but you see libao is not really an audio library in that it does not support formats such as mp3/ ogg/vorbis directly so other libraries need to be included as well. We are working on it but it isn't straight ahead and so far libao just doesn't cut it.
