When trying to emerge 'cheese' from sunrise overlay, it wants to update gstreamer and gst-plugins to unstable version, but gst-plugins ./configure failed complaining gstreamer was too old, I guess the dependencies of gst-plugins do not include gstreamer >= 0.10.17.
Kindly review http://bugs.gentoo.org/page.cgi?id=fields.html#bug_severity
yeah, it's fixed with current gst-plugins-v4l2
