I think the error is an expected environment variable named 'PWD'. It is 
needed to build a path to the Icons folder. You can try to modify the 
line in polyg4qgisUI.py to the correct directory as it is stored on your 
computer.

I'm not familiar with that plugin, so it would be best to ask the author 
here: http://hub.qgis.org/projects/cad4qgis
