There is a problem with the `gstreamer-pbutils-1.0.pc` file

What it has:

Requires: gstreamer-1.0

What it should have:

Requires: gstreamer-1.0 gstreamer-audio-1.0 gstreamer-tag-1.0

I am building 1.14.4 in a properly isolated environment which has no prior gstreamer packages installed whatsoever (I used an ubuntu:18.04 docker container). The change to the pkg-config file (described above) was necessary to get rid of an error (shown below) during the build of gst-editing-services:
