If a log-like FETCH_DEPENDS=python3.8:lang/python38 is written to /usr/local/etc/poudriere.d/make.conf, it can be easily reproduced by poudriere.
Since the default version of python is now 3.8, this will not be reproducible for a while.
Until now, graphics/blender has USES=python:3.8, so there was an environment where python37 and python38 were installed at the same time.
If a port with USES=python:3.9 appears, it is expected to reproduce again.
