MarsSeed [1] filed a deletion request for referencer [2]: Dead package. Missing a dependency. Also the whole dependency chain (several legacy libraries) of libgnomeuimm is unbuildable on gcc 14.
Upstream hasn't published any new release since 12 years ago (2012). [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/referencer/
