It is a python package, that should not be a big deal, though, investigating a bit more "requires" field in setup.py [2], I noticed it depends on specific python libraries, for example oci-sdk 2.10.5, configparser 3.5.0 or six 1.11.0. > > What is the official FreeBSD packaging policy with regards to such python packages?

To port these packages, they should be updated to >= counterparts (patch the setup.py, or source file for those dependencies). Unfortunately this requires additional QA to do properly, as upstream may not have or be currently testing with later versions, and the versions of dependencies in the ports tree can be updated at any time. This is why the vast majority of correctly packaged (upstream) packages use >= dependencies, leaving the x.y.z version specified as the 'lowest supported version' to allow flexibility. Setting *_requires to ">=" upstream, does not prevent upstreams from testing specific versions themselves for their test environment, but its recommended they QA what they distribute, which ensures issues in newer versions of their dependencies are picked up early and often, *before* being released to users.
