setuptools install fails for 34.* on Python 2.6

[DenverJ]

Doing a pip install --upgrade setuptools fails in a virtualenv on Python 2.6. I haven't tested any other configurations.

I see it's building setuptools from source, which is no longer supported. Do you have a late version of pip that can install wheels? If not, you'll need to pre-install the setuptools dependencies manually.

I suspect this issue is a duplicate of #937, only with a slighly different manifestation.

Ah, yes it is. I looked for open issues but didn't think to look at closed. Thanks!

Same problem trying to create virtualenvs in Cygwin. I had to install all setuptools dependencies in order to have it systemwide, but now I don't know how to overcome this when creating virtualenvs.
