You are telling the system that the python_3_ interpreter shall use 3.4, but
not that the general python interpreter shall use it, thus it sticks to 2.7.

  DEFAULT_VERSIONS= python:3.4 python3:3.4

should enable this. You may want to reinstall lang/python and lang/python3
after setting this, so that /usr/local/bin/python links to python3.4.
