gst-element-maker fails when generating derived from element
I'm trying to generate boilerplate for GStreamer Element, derived from GstElement.
For this I run this command:
./gst-element-maker my_element element
Then I get this error:
./gst-element-maker: 383: gst-indent: not found
pkg is gstreamer-1.0
