I see three different other solutions:

1) Link the alsa etc. libraries _static_. If you compile ao yourself,
you'll get only support for the audio systems you actually have; if
your binaries distributor compiles it, he/she can make sure to have
the libraries (and thus ao support) for all.

2) (This works at least on ELF and MS Windows targets): mark the shared
libraries you need not required to run your program.

3) Don't dynamically load your audio stubs, but have them static, and
load the audio libraries themselves. This still leaves us with
dlopen() etc., and although it is cleaner, some audio systems need
various shared libraries, so this adds some fuzz again.

I think 1) is easiest.

Why not? I'm fairly sure I built a static ogg123...

Oh, yeah, the makefile target doesn't work. DIY...
