Author: jaalburqu

New Revision: 1796
URL: http://svn.gnome.org/viewvc/gnomemm?rev=1796&view=rev

Log:
2008-11-17  Josà Alburquerque  <jaalburqu svn gnome org>

	* configure.ac:
	* gstreamer/gstreamermm-0.10.pc.in: Restore gstreamermm dependency on
	gstreamer-base-0.10 because it is in fact needed to build elements
	like Gst::BaseSrc, Gst::BaseSink and Gst::BaseTransform.
