I've had success using virtualenv to install python libs from pip 
without putting them in the global site-packages directory or needing to 
uninstall the distro's packaged versions. With the ubuntu packages 
'python3', 'python-pip' and 'python-virtualenv' installed try

   virtualenv -p /usr/bin/python3 env
   source env/bin/activate
   pip install pyserial
   sudo python MimasV2Config.py /dev/ttyACM0 numato.bin
   deactivate

This creates a directory named "env" that holds the python environment. 
You can change "env" to whatever name you want. After creating the 
environment the first time, subsequent bitstream loads need only

  source env/bin/activate
  sudo python MimasV2Config.py /dev/ttyACM0 numato.bin
  deactivate
