libreadline is out of date in base (both -STABLE and 5.x)
HEAD is the only version thats up to date. This port is only
temp (to make quftp work) until libreadline is updated.
Actually I'm hoping that the submitter will keep maintaining this
PR so that people will have the choice to update their readline
libs. Maybe it could support LIBREADLINE_OVERWRITE_BASE ?
PR: ports/60166
