This looks good to me, but I'm not entirely sure this is the right way to do this, but I can't offer a constructive comment on how to make it better.

If gdb is the only in-tree consumer of libreadline, can we just statically link it into gdb and remove the .so entirely?

[bapt]

@theraven that is what this patch does ;)
@imp yup I could not find a better way either

[theraven]

Or, right, sorry. I misunderstood and thought it was being moved into private. Reading it a bit more carefully, it looks fine.

Can you add the UPADTING entry in here too? This passed an exp run already, correct?

Be sure to highlight reasons for removing it in the commit message - e.g., having ports use readline from ports allows it to be kept up-to-date. Specifically, it's not just because of the GPL that it's being removed.

Here's my take:

20140707:
        The GNU readline library is now an INTERNALLIB - that is, it is
        statically linked into consumers (GDB and variants) in the base
        system, and the shared library is no longer installed.  The
        devel/readline port is available for third party software that
        requires readline.
