I think, you are misinterpreting something or I am not getting what you both are up to. The advice from the mail in October handles the following situation: 1) Joe User uses Python X as default 2) Joe User wants to install a port PP for Python Q 3) To avoid conflicts, Joe User has to a) install PP with PYTHON_VERSION=Q - or - b) set up a poudriere with with Python X as default (DEFAULT_VERSIONS=...) and a make.conf entry setting PYTHON_VERSION=Q This is necessary to avoid build and installation conflicts for packages, which support different Python versions (X and Q) at the same time, packages, which can be installed concurrently, etc. Cheers Marcus
