You're missing python-serial. Can you add deps=serial to the [testenv:driver] section in tox.ini and see if that works?

Added serial to tox deps and it gets a bit further, any thoughts? as before UNKNOWN-0.0.0.zp can't be write, and now we have no module named chirp. Is there something to be done with the build first? Thanks. Nicolas
