schnecki [1] filed an orphan request for libgnomeuimm [2]: There was a version update. Unfortunately they use the version 2.8 as new version number, although 2.28 is considered higher. See https://download.gnome.org/sources/libgnomeuimm/ This causes problems when this package is a requirement: E.g. libgnomecanvasmm>=2.26.0 for referencer. Because version 2.8 is considered older [1] https://aur.archlinux.org/account/schnecki/ [2] https://aur.archlinux.org/pkgbase/libgnomeuimm/
