The Setup
OS: Ubuntu 20.04.2 LTS
Gstreamer: v1.16.2 (installed via apt)
I downloaded tag 1.16.2 of gst-plugins-bad and executed the following:
cd gst-plugins-bad/tools
./gst-element-maker myelement elementand got the following ouput:
/gst-element-maker: 383: gst-indent: not found
pkg is gstreamer-1.0
