 That doesn't really make sense. There's nothing else in the buildlink
 tree that leads to either harfbuzz or glib2 besides libass, so in
 order to generate this error it must be linking with harfbuzz.
 
 When I build it on NetBSD I get a shared lib that depends properly on
 both harfbuzz and glib2.
 
 Also, unless ffmpeg reexports libass's API (reasonably certain it
 doesn't) it's not correct to include it directly in the bl3.
 
 Are your sure your harfbuzz library got built correctly? If it didn't,
 it might be missing its own dependency on glib2 and that would (or at
 least could) generate this failure.
