Release 3.6.9 is breaking on docker alpine

[laveesingh]

I'm trying to install xhtml2pdf on a python:3.9-alpine docker image.
The reportlab package is as a dependency to xhtml2pdf. It was working alright up till version 3.6.8 , but version 3.6.9 cannot be installed on alpine linux, it throws the following.
