ebuild missing alsa,arts or some dependency that have to treat in USE flags. for example gnome-sound-propaties detect my soundcard after gst-plugins-alsa installed "by a hand" despite set in USE flags. note that preview version has some use flags. 0.10.14: >IUSE="alsa esd oss X xv" 0.10.15: >IUSE="debug nls" log when launch gstreamer-propaties: Gtk-Message: Failed to load module "atk-bridge": libatk-bridge.so: cannot open shared object file: No such file or directory (gstreamer-properties:26276): Gnome-WARNING **: Accessibility: failed to find module 'libgail-gnome' which is needed to make this application accessible (gstreamer-properties:26276): Gnome-WARNING **: Accessibility: failed to find module 'libatk-bridge' which is needed to make this application accessible gstreamer-properties-Message: Skipping unavailable plugin 'alsasink' gstreamer-properties-Message: Skipping unavailable plugin 'artsdsink' gstreamer-properties-Message: Skipping unavailable plugin 'esdsink' gstreamer-properties-Message: Skipping unavailable plugin 'osssink' gstreamer-properties-Message: Skipping unavailable plugin 'pulsesink' gstreamer-properties-Message: Skipping unavailable plugin 'sdlvideosink' gstreamer-properties-Message: Skipping unavailable plugin 'v4lmjpegsrc' gstreamer-properties-Message: Skipping unavailable plugin 'qcamsrc' gstreamer-properties-Message: Skipping unavailable plugin 'v4lsrc' gstreamer-properties-Message: Skipping unavailable plugin 'v4l2src' gstreamer-properties-Message: Skipping unavailable plugin 'alsasrc' gstreamer-properties-Message: Skipping unavailable plugin 'esdmon' gstreamer-properties-Message: Skipping unavailable plugin 'osssrc' gstreamer-properties-Message: Skipping unavailable plugin 'pulsesrc'
typo: preview -> previous
File bugs about missing dependencies in ebuilds, not about missing use flags that were removed intentionally since they were completely bogus.
this breaks gnome-sound-propaties, mixer_applet2, totem for using on alsa. control-center still has alsa, but hasn't gstreamer pulled alsa plugins? [ebuild R ] gnome-base/control-center-2.20.1 USE="alsa hal -debug -eds -esd"
Once again, file separate bugs is something is missing a dependency.
