Comment (by dliessi):

 See https://gitlab.gnome.org/GNOME/librsvg/-/merge_requests/309, already
 merged in the development branch but not yet cherry-picked in the stable
 branch.

 Maybe the library uses harfbuzz only through pango, while the tests check
 for harfbuzz directly.

 Should we add an explicit dependence on harfbuzz?
 And maybe freetype as well (`configure.ac` checks for both).
