At this point I don't think pandas_datareader was installed by MacPorts, but rather by pip. This was after an OS upgrade to Catalina where I thought all ports were removed and reinstalled. But evidently pip installations were not deleted even though python was uninstalled. After upgrading pandas_datareader through pip the problem went away so this ticket can be closed.

Correct, uninstalling a port only uninstalls the files that port installed, not files that you might have created by using that port (such as things that you might have installed using pip).

We don't have a py-pandas-datareader port but if you'd like to submit one, please do. Or maybe Andrew will create one since he maintains a lot of other Python ports.
