Of course, I could just spell the frickin' option correctly. --without-ensurepip works a lot better than --without-ensureip. :p python34 3.4.0-2 now never installs setuptools/pip. I've also added py34 variants to setuptools-tng-py and pip-py. Continue to depend on setuptools like always. This way we retain control over the setuptools version separate from python. Daniel
