The other thing is there are a couple of ABI incompatibilities between the libreadline version we have in base and newer libreadline which is getting = more and more use making it more complicated to manage ports that requires newer readline. regards, Bapt --GLp9dJVi+aaipsRk Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iEYEARECAAYFAlO9z3AACgkQ8kTtMUmk6Ew4IACfQ6mRfHJ9enFb436Hq/XGZoEZ Vv0AnAwwmjkVFLYCzyhPSZOI4Nq9k1+k =8NkS -----END PGP SIGNATURE----- --GLp9dJVi+aaipsRk--
