'enum; python_version == "2.6" or python_version=="2.7"'
It turns out that when you build a wheel the environment setting gets stripped off. Later, when installing the wheel with pip, the environment setting is not there, and pip tries to install enum even on Python 3, leading to an error.
I am working on a patch for this, I'll submit a PR soon.
