Like to get the gnucash working on x86, it needs a updated version of dev-db/libdbi (#465716). Why not bump libdbi-drivers too so you can remove: "DEPEND=">=dev-db/libdbi-drivers-0.8.3" # On purpose, libdbi-drivers 0.8.4 does not exist" from ebuild.
#465716
ebuilds attached to #455134 work fine and gnucach problem is solved. See https://bugs.gentoo.org/show_bug.cgi?id=455134
