When Gstreamer is not installed, emerging gnome-base/gnome-settings-daemon would bring error message saying about missing gstreamer library. I don't need some dependencies pulled by packages in gnome-light and one of them is gstreamer, actually pulled by control-center and gnome-settings-daemon ebuilds. gnome-settings-daemon is built with gstreamer support, even though `configure` script reports that this support is not enabled. Through externally specifying `--disable-gstreamer` argument to `configure` would solve problem and gnome-settings-daemon will not link to gstreamer libs. Ebuild has external gstreamer USE flag, but for some reason it won't pick it. Looking in ebuild revealed that there is wrong call to pkg_config. Fix: Replace pkg_setup call with pkg_config.
Looks like there's a typo in the ebuild -- it uses pkg_config instead of pkg_setup.
thanks for spotting this. Fixed in CVS.
