installed and a build failure

     Type:  defect    |     Status:  new
 Priority:  Normal    |  Milestone:  MacPorts 2.6.0
Component:  base      |    Version:  2.5.99

----------------------+----------------------------
 With base master (bc008721189ff719dc1ac70a06a476ff6013c63b), dependencies
 for python projects seems incorrect.

 I'm trying to install certbot +python37.  It's pulling in dependencies on
 python 2.7 modules:
