Where should PangoFt2 be installed?

I am trying to get GraphViz 13.1.2 to build from source on macOS Sequoia 15.7. When I run configure without any options, it seems to find Pango and Cairo and Pangocairo OK, but configure fails with this error:

No package ‘pangoft2’ found

I don’t see this listed anywhere as a GraphViz dependency, and I have no idea which of the GTK+ packages might have tried to build it and failed due to cyclic dependencies in some of the build setups (there are a few, it seems).

Here is what I have from pkg-config:

Alll packages seem to have sensible output from running pkg-config with the --cflags and --libs options. Let me know if I should post the complete output from running configure.
