When emerge sox (with alsa in my USE flags) sox failed ALSA checks and reported that it would not be including alsa support, despite the fact that I have the required libs installed (I believe).

let me guess... Are you using the builtin kernel modules and linux-headers-2.4.x?
Yes, I am. All the 2.6.x headers are masked, however.
Thought so =) I just put together alsa-lib-1.0.5-r1 which should handle this problem. Pleasse give it a try and let me know (it should notice you don't have a /usr/include/sound and setup the symlink to /usr/src/linux/include/sound) which are the alsa-driver headers
Yup. It works. :-) Just curious, when will the 2.6.x headers be unmasked for x86?
I honestly don't know... try asking on #gentoo-dev.
