Yes.

When the py*-readline dependency was replaced with py*-gnureadline in ports, those ports' revisions should have been increased to have that change properly recorded in users' MacPorts registries, but that was forgotten:

https://github.com/macports/macports-ports/commit/0b90afa746b9f8935317e6300cd1adc15213234e

I've increased the revision of 3 of the 4 affected ports now:

https://github.com/macports/macports-ports/commit/b0da1e5aee356a6c41d745cc868cec44ba2568a5

The 4th has already been updated in the mean time.
