py27-certbot fails to run

[Carmel NY]

FreeBSD 11.1-RELEASE-p10

Name           : py27-certbot
Version        : 0.25.0,1
Installed on   : Sat Jun  9 17:18:31 2018 EDT
Origin         : security/py-certbot

Yesterday I updated the security/py27-certbot port to version 0.25.0,1
without incident. When running the application via port last night, it
produced this error output:

Traceback (most recent call last):
  File "/usr/local/bin/certbot", line 6, in <module>

in resolve raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'requests-toolbelt>=0.3.0'
distribution was not found and is required by acme

Is this something local to my machine only or should I file a PR against it
and what can I do to alleviate the problem?
