Ah, I thought that I was already subscribing to this bug ticket.

The problem is:

This is exactly true and if we use readline 6 and make ruby's readline.so
linked against both libreadline.so and libruby.so, ruby "itself" (not ruby's
readline module only) must be GPLv3 compat , so b) is not the option.
(By the way on Fedora not all softwares using readline have switched to GPLv3
 compat license, so currently Fedora ships both readline 6 and readline 5)

Well, the license issue is always really annoying , however I hope this issue
is resolved somehow.
