It's an Amazon Linux instance, and using their packages, which seem a
bit odd (there's nothing in /usr/local/include). Maybe we should be
looking at INCLUEPY?


[ec2-user@ip-172-31-22-42 bf]$ python3 -m sysconfig | grep include
    include = "/usr/local/include/python3.6m"

I have upgraded it to python 3.8, but got similar results.
