Comment (by roman.klesel@…):

 I don't really know how to contribute here nor do I have detailed
 knowledge about how macports really work but I guess updating pbr and
 stevedore to current versions would be a good solution.
 I have attached a diff that suggests exactly this. However untested ...
 didn't see how I could run a test without further digging through docs.
