We have a framework for that, see
pkgsrc/lang/python/versioned_dependencies.mk.  The standard procedure
is to import the last python 2.x version under a different directory,
limit it to python 2.7, switch all users to versioned_dependencies.mk
and update the existing package to the latest version, limiting it to
python 3.x.

The packages won't conflict because the PKGNAMEs are py27-* and py3*.
