> I was working on packaging taffybar (https://github.com/taffybar/taffybar), which depends on haskell-gi (https://github.com/haskell-gi/haskell-gi) - haskell bindings for goject-introspection capable libraries. While packaging gi-gdk, I hit this error:

These errors can also be caused by dependent libraries not being found,
or linker errors, etc.  I would suggest to run `ldd` on the .so itself
(from glibc), and see what the output is.

Grafts are applied after all packages have been built, so it is normal
that the build environment would see and use the ungrafted gtk.

Best,
