@aanderse See #56943.

You need to disable strictDeps like the commits that reference the issue until we can fix it.

Yeah I have seen one of these already and didn't have time to test/fix this tonight so just wanted to get it logged. I'll self assign and circle back to this hopefully in the next few days.

@worldofpeace in this case adding strictDeps = false; did not fix the issue, but adding gobject-introspection to buildInputs did.
