MarsSeed [1] filed a deletion request for gmpc-git [2]: All development ceased 4 years ago. Dependency gob2 from 2013 is a broken orphan. Even when gob2 still worked, this was failing to build (see last comment from 2023). [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/gmpc-git/
