Gnokii has a newer version 0.5.4 renaming the ebuild seems to be sufficient Reproducible: Always Steps to Reproduce: 1. 2. 3.
well, i've been working on re-writing the gnokii ebuild which removes the gnokii group requirements and re-enables sandboxing. can you please check if the one in portage works for you and maybe there might be things that need improving? thanks.
haven't heard back so i assume all is well. otherwise, reopen or file a new bug if there are problems.
