gst-build 1.14 on Ubuntu 16.04 isn't working for me

After Carl's suggestion I executed the following ...

sudo apt install --yes gobject-introspection libglib2.0-dev


... and I get further but I am now blocked by this error:

subprojects/gstreamer/gst/meson.build:272:4: ERROR:  gobject-introspection
dependency was not found, gir cannot be generated.


Here is the full terminal output:

But I just installed the gobject-introspection package.

I made sure to close the terminal and re-open it (in case I needed some new
environment variables from the package install) but it didn't help.
