Building GStreamer using Cerbero failing.

[North48]

I'm trying to install the latest GStreamer 1.12.3 (or close to it) on a new
install of Raspbian Stretch.  Apt-get installs an older version. So I
followed the suggested steps in:
https://gstreamer.freedesktop.org/documentation/installing/building-from-source-using-cerbero.html

git clone git://anongit.freedesktop.org/gstreamer/cerbero
cerbero bootstrap
cerbero package gstreamer-1.0

The last step crashes as shown below (last section of output copied).  Not
sure what I did wrong.  Is there another way to install the latest
GStreamer?
