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.

compilation of LaTeX documents. This includes compiling the document
itself, of course, enough times so that all references are defined, and
running BibTeX to manage bibliographic references. Automatic execution
of dvips to produce PostScript documents is also included, as well as
usage of pdfLaTeX to produce PDF documents.
