MarsSeed [1] filed a deletion request for futhark [2]: Abandoned, broken package from 2022. Last maintainer said it is not worth for them to put in the effort to make and keep this build working.
It is recommended that people use the functioning, much newer AUR/futhark-bin. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/futhark/
