Yep so:
*_DEPENDS=${PYTHONPKGNAMEPREFIX}foo<vspec>:port/origin@${PY_FLAVOR}
Is the correct method, in which PY_FLAVOR gets derived from
DEFAULT_VERSIONS, following the frameworks default versions over time,
and honoring user default preferences and selection.
With USES=python:env to bring in the relevant variables for use.
One just needs to *also* make sure that for any scripts provided in the
dependent port, they use ${PYTHON_CMD} for shebangs, etc, rather than
env python env python2, env python3, who's targets change over time
(depending on the default version)
