  1. Get a list of requested Python versions with pyversions(1)
  2. Perform build with each of the requested Python versions

Ad 1: You're using pyversions already, but only to get the default
Python version. Use -vr instead of -vd to get a list of requested Python

Ad 2: I'm not entirely clear on the structure of your program or how the
build process works -- there's a setup.py, but in debian/rules you
build/install manually -- but something like this should work:

	# Get the supported Python versions
	PYVERS = $(shell pyversions -r -v)

	set -e -x;\
	for py in $(PYVERS); do \
                PYTHON=python$$py make -C source;

Substitute python with $(PYTHON) where appropriate

Again, I didn't look into your build process in detail, so adjust the
above to your needs. For example, the above really performs the entire
build process twice. If Python is involved in only a subset of the
steps, it would be better to iterate there instead.
