OS X, lyqi and rumor?

[Christopher Suckling]

In The LilyPond Report #4
<http://valentin.villenave.info/The-LilyPond-Report-4>, there is a
video in which Nicolas Sceaux demonstrates his lyqi quick insert mode
he wrote for Emacs.

The video appears to demonstrate a lyqi+rumor combination running
under OS X. Unfortunately, I have fallen at the first hurdle
attempting to compile rumor on OS X 10.5.2 - rumor requires ALSA which
is, of course, not available for OS X.

So my question to Mr Sceaux (or anyone else who has successfully used
this combination) is how did you do it?

Best wishes,

Christopher
