If a package requires specifically python version 2.7, it will be installed, as well as all the relevant modules; you may have already, say, PYTHON_VERSION_DEFAULT=39 in /etc/mk.conf, but if a package specifies another version, it will get it. Usually there are no problems with this, except when a package installs executables without the version of python appended to the name. I recently switched my primary development machine from python3.7 to 3.9, replacing all modules and rebuilding all packages requiring python v.3, it took me some time, but eventually I was able to remove python38 and python37, I am left at the moment only with python27 and 39. There are still quite a few packages with PYTHON_VERSIONS_ACCEPTED = 27. -- ----
