Somewhere around here I said I had too many USE flag staatements under /etc/
portage, so I removed package.use and just set whatever flags were needed to 
install all my packages. That was fine, but it meant that USE=pulseaudio was 
only set on alsa-plugins, which was fine as far as it went, but nothing else 
could use PA. Now that I've put pulseaudio back into make.conf and recompiled, 
I hope for a quieter life, if you see what I mean...

Thanks again for everyone's patience.
