KLV stream not detected

For whatever reason, it looks like I used
git://anongit.freedesktop.org/git/gstreamer/$module
to grab my initial install and just do 'git pull origin' to get updates.
I found a script from last August that used this as the source and this
is also in the gst-plugins-good.doap file in my gst-plugins-good build
directory. I haven't has a need to learn too much a git so I'm not sure
how different this might be from what is on github (or how to tell).
