At first sight I would say that you are not using pulseaudio on your system, since it seems gstreamer cannot connect to the pulseaudio streamer. Try changing "pulsesink" with "osssink" or "alsasink" in the gst_parse_launch call. If none of those help, I'm also at a loss: I am not a gstreamer expert...

A .lpi file must be opened with project - open menu.
Then I tried to see if I can get it going on the commandline but trouble

This is a typical error when you do not have the gstreamer1-0-dev package
installed.
normally,
sudo apt-get install libgstreamer1.0-dev
will fix this.
Alternatively, you can try to change the code
gstreamerlib = 'libgstreamer-1.0'; {Setup as you need}
to
gstreamerlib = 'libgstreamer-1.0.so.0'; {Setup as you need}
