I should say that the nasty solution that I have now is a temporary
Makefile in <working_tree>/scipy/scipy/io/matlab:

TMP_BUILD = $(HOME)/tmp/scipy-matlab-files

py3-py:
	rsync -r --delete . $(TMP_BUILD)
	cd $(TMP_BUILD) && 2to3 -w *.py tests/*.py && python3 setup.py build_ext -i

and I link $(TMP_BUILD) as <installed_packages>/scipy/io/matlab

See you,

Matthew
