[reportlab-users] Error in piecharts.py

[Eldon Ziegler]

After installing reportlab via pip with Python 3.6, we get
Successfully installed reportlab-3.5.31

but

File "/opt/rh/rh-python36/root/usr/lib64/python3.6/site-
packages/reportlab/graphics/charts/piecharts.py", line 1314, in draw
  fixLabelOverlaps(L,sideLabels)
NameError: name 'sideLabels' is not defined

piecharts.py shows 
__version__='3.3.0'

Thank you,
Eldon Ziegler
