I'm trying to build a Pants `pex`, any idea why when I run `/tmp/pantsbuild/pants --pants-config-files=pants-production.ini clean-all binary //:pants`   in my repo I get this error: ```Exception caught: (&lt;class 'pex.resolver.Untranslateable'&gt;)

Exception message: Package SourcePackage(u'file:///Users/charleshunt/projects/depot/.pants.d/python-setup/resolved_requirements/CPython-2.7.10/setproctitle-1.1.10.tar.gz') is not translateable by ChainedTranslator(WheelTranslator, EggTranslator, SourceTranslator)
