This happened when upgrading py27-setuptools_scm from @2.0.0_0 to @3.1.0_0. The problem went away if I deactivated @2.0.0_0 first.

The setup.py file says:

important note:

the setup of setuptools_scm is self-using,
the first execution of `python setup.py egg_info`
will generate partial data
its critical to run `python setup.py egg_info`
once before running sdist or easy_install on a fresh checkouts

pip usage is recommended

Is the port doing that?
