Followup: I just solved my own problem, so I can share my story in case it helps...
My system (a big shared cluster) has a modular system for loading/unloading standard packages, including Python. The standard python2 provided by the system is somewhat older (2.7.3, as you can see from the paths in my traceback), so gcc was finding the wrong libraries. When I unloaded the system Python, gcc couldn't make the same mistake and my build succeeded. So you may similarly need to figure out how your build is finding outdated local Python libraries and suppress them; it would be hard for me to say more without more information, such as your build log.
