Unfortunately, libao 1.0.0 does *not* build on Mac OS X 10.5, because it uses 10.6-only stuff; on a quick glance I noticed AudioComponentInstance (which is new in 10.6); I asked some people to test compilation on 10.5 and they confirm that there is a build error, see below.

Changing AudioComponentInstance to ComponentInstance should work on both 10.5 and 10.6, but ideally, somebody with a 10.5 machine should go over libao and verify that it compiles and works.

Cheers,
