"Broken files found, but all associated ports are not in the index" error

[Greg Earle]

On a 2010 Mac Pro running macOS Mojave 10.14.6, I'm getting this:

--
[0:48] nightowl:/ % sudo port upgrade outdated
Nothing to upgrade.
--->  Scanning binaries for linking errors
--->  Found 2 broken files, matching files to ports
Warning: No port p5.26-net-ssleay found in the index; can't rebuild
--->  Broken files found, but all associated ports are not in the index 
and so cannot be rebuilt.

[0:49] nightowl:/ % port installed p5.26-net-ssleay
The following ports are currently installed:
   p5.26-net-ssleay @1.900.0_0 (active)

[0:50] nightowl:/ % port info p5.26-net-ssleay
Error: Port p5.26-net-ssleay not found
--

Tried to remove it but it didn't like that:

--
[0:52] nightowl:/ % sudo port uninstall p5.26-net-ssleay
Note: It is not recommended to uninstall/deactivate a port that has 
dependents as it breaks the dependents.
The following ports will break:
  p5.26-io-socket-ssl @2.68.0_0
  p5.26-http-tiny @0.76.0_0
  p5.26-io-socket-ssl @2.69.0_0
  p5.26-io-socket-ssl @2.70.0_0
  p5.26-io-socket-ssl @2.71.0_0
Continue? [y/N]: N
--->  Cleaning p5.26-net-ssleay

Is there anything I can do about it?  I still have a ton of p5.26-* and 
p5.28-* ports installed, as well as p5.30-*.

[0:54] nightowl:/ % sudo port installed | grep p5.26 | wc -l
      134

Thanks,
