Problem with gst rtsp server

[Paulo Paiva]

I am having this problem with the code listed bellow

$ make
gcc `pkg-config gstreamer-0.10 gst-rtsp-server-0.10 --libs` `pkg-config
gstreamer-0.10 gst-rtsp-server-0.10 --cflags` -o server server.c
$ ./server
./server: symbol lookup error: /usr/lib/libgstrtspserver-0.10.so.0:
undefined symbol: gst_plugin_feature_rank_compare_func


Can someone help me?
Thanks all!
