We actually distribute Ruby with readline binding. A user may link the binding with readline6, which we do not intend. If it is allowed, we can distribute a product using GPLv3 library with license that is imcompatible with GPLv3, I guess. Even so, can we distribute Ruby without the note prohibiting such a link? IMHO, I agree with your opinion, but I'm not a lawyer. I cannot determine. License issue sucks. -- Yusuke Endoh <mame / tsg.ne.jp>
