I installed all necessary dependencies. I don't know what's wrong. Help?
OS: Debian 11 (bullseye/testing)
Packages installed: golang, libhandy-0.0-0 libhandy-1.0 gob2. I'm using gnome so gtk should be already installed.

Those dependencies don't seem to include gio nor glib nor gobject, but I
don't use Debian, so I'm not sure.

@diamondburned what distro do you use and what are the exact package names?

		gnome3.glib gnome3.gtk libhandy
	];
