It means /usr/local/bin/gst-launch-0.10 uses the
(older) /usr/lib/libgstreamer-0.10.so from the default prefix.

Try (in your shell, before running gst-launch-0.10), something like:

 export PATH="/usr/local/bin:$PATH"
 export LD_LIBRARY_PATH="/usr/local/lib:$LD_LIBRARY_PATH"
 export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH"
