I get this :

valac -d '/home/john/Documents/Vala/tests/bin' -g   --pkg "glib-2.0"  --pkg "gdk-2.0"  --pkg "gmodule-2.0"  
--pkg "gtk+-2.0"  --pkg "gstreamer-0.10"  "/home/john/Documents/Vala/tests/test.vala" -o "test"
test.vala: In function ‘test_run’:
test.vala:53: warning: passing argument 2 of ‘gst_pad_add_buffer_probe’ from incompatible pointer type
/usr/include/gstreamer-0.10/gst/gstutils.h:1117: note: expected ‘GCallback’ but argument is of type ‘gboolean 
(*)(struct GstPad *, struct GstBuffer *, void *)’
