But that shouldn't happen, since harfbuzz is recommended (not directly, but it is) for cairo. I'll do the following: - on the harfbuzz page: note that the optional dep on cairo is circular, and that it is recommended to build harfbuzz first - on the cairo page: remove the optional dep on harfbuzz (it is already in the recommended chain), which can only add confusion.
