Bugzilla Bug 59051

during emerges I get:
 * Caching service dependencies...
 *  Can't find service 'alsa-sound' needed by 'slmodem';  continuing...

In my case, the service is /etc/init.d/alsasound, not alsa-sound.
a quick check seems to show that alsasound is used in the more recent ebuilds, though I vaguely remember alsa-sound being used previously
