You are correct.

It looks like in commit 1eeb59a2099 you added the libharfbuzz
dependency (6 months ago).
But you did not include this change in the Changelog. I will guess
that downstream packagers, including Debian and whoever it is who
builds unofficial binaries, missed this new dependency. Hence, their
packages are broken.

Please fix this, Paul. Those folks shouldn't need to wade through
every commit message in order to build ffmpeg correctly.
