Nick et al,

currently trying b3 and using the bundled pip (1.5.2) to update the bundled setuptools from 2.1 to 2.2 on Windows 7 and I get the following. Any idea if this is still an issue with the newer versions (and thus might be relevant to this case)?

F:\Python34>Scripts\pip3.4.exe install -U setuptools
Downloading/unpacking setuptools from https://pypi.python.org/packages/3.4/s/setuptools/setuptools-2.2-py2.py3-none-any.whl#md5=3b7d84f496aed8c07b91efba4aa197a4
