Well, uninstalling the system packages is probably going to be quite
disruptive to your system, but having gstreamer installed both in /usr
and /usr/local is likely going to lead to some weird behaviour and
bitrot sooner or later too (when packages get upgraded and you have
forgotten that you installed a custom GStreamer from source)..

For development/testing purposes it might be best to uninstall
everything in /usr/local/lib (run 'sudo make uninstall' in your source
trees) and either install it into some custom prefix like /opt or
~/gstreamer and set up your environment (PATH, PKG_CONFIG_PATH,
LD_LIBRARY_PATH) to use that version when needed, or run an
'uninstalled' GStreamer setup (gst-uninstalled) in your home directory.

Depends what you're trying to do how I guess.

Or you try to make your own packages with the new versions and install
those over the older system ones.

Cheers
