python install, gclient.py error

Hello, when I try pip install v8eval, I run into an error with a gclient.py command that seems to be used on build. I'm happy to dig around, but a quick search didn't bring up much info. Log below (note that in the log I was using anaconda, but ran into the same area with my system python).
