rpicam error with little configuration

[warrenjb]

Anyone working on the below or is it a problem with my install?

I can see an image using ssh with raspistill -o test.jpg but the camera button within the UI yields a black screen. Traced this back to below:

pi@CRANKSHAFT-NG:~ $ sudo /opt/crankshaft/cameraserver.py
/opt/crankshaft/cameraserver.py:9: DeprecationWarning: the imp module is deprecated in favour of importlib; see the module's documentation for alternative uses
import imp
Traceback (most recent call last):

ModuleNotFoundError: No module named 'PIL'

Using a RPI 3+ with latest armhf install and with rpicam 2.1.
