Want to build Appplication on Beagle Board

Hi Everybody,
                    I have built angstrom image online via narcissus.
I have taken each packages. Now i would like to build gst-player-0.0.0
on beagle board. Because totem is very slow and consuming lots of
memory as well as cpu usage. In its option i would like to go with gst-
player. To build gst-player on beagle board i need header files and
librarieson its dependent packages and also pkg-config utility. i
could not find these required things in the rootfs of angstrom.

                    Can anyone guide me how can i make it possible or
is there any other way to build gst-player.

                    Please correct me if i am wrong.

Thanks In Advance,

opkg install gst-player ?
