Yes I did.

The example code is the following:

#include <iostream>
#include <gstmm.h>

using namespace std;

int main (int argc, char* argv[]) {
   Gst::init(argc, argv);

   Glib::RefPtr<Gst::Element> element =
       Gst::Element::create("fakesrc", "source");

   if (!element) {
       cout << "Failed to created gst element." << endl;
   }
}

I got gstreamermm from the svn link given to me by Milosz:

http://svn.beep-media-player.org/gstreamermm/trunk

I applied the attached patch in the top level directory to fix some 
things in autogen.sh (but this part is already in svn so just skip this 
part of the patch), the <gstmm.h> include file and a compile error I was 
getting reported in the following thread: 
http://mail.gnome.org/archives/gtkmm-list/2007-November/msg00114.html.
