This a problem with the gobject-introspection package.
_giscanner.dll is linked with python2, but the shbang names 'python',
which is now python3.
I have been working on rebuilding this package, but not quite there yet.
You can work around this by fixing the shebang in /usr/bin/g-ir-scanner
to explicitly name python3.
The log of my last successful build of harfbuzz shows that python-3.6
was installed. Do any of the python experts out there (Marco? Jon?)
know what the problem could be?
