net-nds/openldap-*.ebuild does preserve_old_lib "${ROOT}usr/$(get_libdir)/..." preserve_old_lib_notify "${ROOT}usr/$(get_libdir)/..." but preserve_old_lib{,_notify} itself adds "${ROOT}" to each argument: (from eutils.eclass) --- for lib in "$@" ; do [[ -e ${ROOT}/${lib} ]] || continue ---
Fixed in CVS, thanks for the notify
