I believe that we don't want both MODPY_DEFAULT_VERSION_3 and the python3 FLAVOR. Additionally, the upstream supports Python 2, but I don't think we want to add Python 2 support to ports, in which case we'd enforce python3 with FLAVORS = python3; FLAVOR = python3. Although I'm not quite clear on whether a program written in python should use the FLAVORS/FLAVOR style or continue to use MODPY_DEFAULT_VERSION_3. At any rate, the program works for me (that is, it turns SVGs into smaller SVGs that appear to look the same).
