about compiling error on gnome-media

I'm compiling gnome-media, but get some problem. I installed gstreamer
before the compiling. And then do "./configure", then "make". But the
"make" suggests as follows...

/****************************************************************************************/

Could anybody tell me how to solve this problem? That will be very
appreciated!
