mbunkus [1] filed a deletion request for iftop-devel [2]: The community/iftop package now uses the same upstream version and the appropriate patches that this package provides. Therefore there's no use for iftop-devel anymore. Thanks. [1] https://aur.archlinux.org/account/mbunkus/ [2] https://aur.archlinux.org/pkgbase/iftop-devel/
