The most likely reason for this is that you compiled against a newer
version of the GStreamer includes and GStreamer library (maybe compiled
from source and installed into /usr/local/?), and that at runtime the
system picks up an older version of GStreamer, e.g. a GStreamer
installed from packages into /usr/lib.

Maybe you didn't run 'sudo ldconfig' after doing 'make install'.

Maybe you need to add /usr/local/lib/... to the LD_LIBRARY_PATH
environment variable or /etc/ld.so.conf*

You can check which GStreamer it picks up via:

 $ ldd /usr/local/lib/gstreamer-1.0/libgstmyplugin.so | grep
libgstreamer
