Comment (by ryandesign):

 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?
