Tried to run configure

[Robin Raymond]

I did the recursive pull, installed Python 2.7.x (latest) and got this when I ran the scripts:

  File "C:\Python27\lib\multiprocessing\forking.py", line 358, in get_command_line

            This probably means that you are on Windows and you have
            forgotten to use the proper idiom in the main module:

                if __name__ == '__main__':
                    freeze_support()
                    ...

            The "freeze_support()" line can be omitted if the program
            is not going to be frozen to produce a Windows executable.

I'm not a python expert to know what to do here... FYI - VS2013 on Win8.1

This can be fixed by disabeling parallel support in gyp, either by command line arguments in configure.py or by editing
build/gyp/pylib/gyp/init.py line 392 into
options.parallel = False
