'module' object has no attribute 'RAND_LIMIT'

Currently, running python python/gps/gps_main.py box2d_arm_example
leads to the following error:

DEBUG:No gps_agent_pkg: gps_agent_pkg

This is probably a problem with my installation of box2d; still, please take a look.

This is most certainly an issue with your box2d installation

This is a temporary solution to the issue, and it's not an issue with gps per se:

1. Clone this repo
2. Follow the Box2d setup, but
   do not clone pybox2d (it is seemingly broken at the moment), instead do
   pip install box2d-py
