Thanks for those hints, but I don't think it's the issue in my case. If
I take net/py-pysocks for example it is marked USES=python:3.6+ .. but
it fails with [00:02:18] [04] [00:00:00] Finished net/py-pysocks@py39 | py39-pysocks-1.7.1: Ignored: Unknown flavor 'py39', possible flavors: py311

A case in point: I wanted to build sysutils/py-salt via Poudriere with a default Python flavour of 3.10.  It failed.  Looking in the Makefile, I saw "USES= cpe python:3.6-3.9".  Most other ports tend to have "... python:3.6+", but this one said it only worked with 3.6 to 3.9.  Hence, trying to build it with 3.10 failed.
