To continue what was discussed ont he bug, you seem to have forgot to
set your run-time env. Adding symlink to some random place won't make
it work. Best is to setup a prefix env, please fix for your needs, this
is just pure guessing from the dump you gave.

  export LD_LIBRARY_PATH=<prefix1>/lib:<prefix2>/lib:...
  export GST_PLUGINS_PATH=<gstprefix1>/lib/gstreamer-1.0:<gstprefix2>/lib/gstreamer-1.0:...

Verify you setup using gst-inspect-1.0. In general, using as many
prefix as there is component generates a lot of setup and is
complicated. So if you want to keep it this way, then I guess you'll
have to work harder.
