I am installing gst-plugins-x-0.10.6 and: chmod 644 /var/tmp/portage/gst-plugins-x-0.10.6/image//usr/lib/gstreamer-0.10/libgstximagesink.a i686-pc-linux-gnu-ranlib /var/tmp/portage/gst-plugins-x-0.10.6/image//usr/lib/gstreamer-0.10/libgstximagesink.a libtool: install: warning: remember to run `libtool --finish /usr/lib/gstreamer-0.10' make[1]: Opuszczenie katalogu `/var/tmp/portage/gst-plugins-x-0.10.6/work/gst-plugins-base-0.10.6/sys/ximage' dodoc: README does not exist >>> Completed installing gst-plugins-x-0.10.6 into /var/tmp/portage/gst-plugins-x-0.10.6/image/
