if a port needs 2.x then set MODPY_VERSION=${MODPY_DEFAULT_VERSION_2}.
This commit doesn't change any versions currently used; it may be that
some ports have MODPY_DEFAULT_VERSION_2 but don't require it, those
should be cleaned up in the course of updating ports where possible.
Python module ports providing py3-* packages should still use
FLAVOR=python3 so that we don't have a mixture of dependencies some
using ${MODPY_FLAVOR} and others not.
texlive_texmf-minimal (pkgpath print/texlive/texmf,-main), because
nobody knows how the texlive interdependencies will change in the
future.
While here, be nice to SUBST_VARS and give yet another space and a
tab, too.
