That's the wrong way to do it. There's no runtime dependency on alsa, so
it's just incorrectly set in the RPM file. Removing the alsa plugin just
removes functionality, which isn't a good thing.

I'm not sure about libvorbisenc - it's possible that this we did this
(changing the .so version number) incorrectly, in which case a symlink
is safe. However, there is a real incompatibility in libvorbisfile. It's
in a single function, which is rarely used (xmms will use it with some
non-default options turned on, I don't know if any other current programs
use it).
