Comment (by mascguy):

 This error occurs when the Python bindings aren't able to be built
 successfully.

 I'm seeing the following in the logs. It looks like there's in an issue
 with `py39-numpy`:

 :info:configure IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE
 THIS ISSUE!
 :info:configure Importing the numpy C-extensions failed. This error can
 happen for
 :info:configure many reasons, often due to issues with your setup or how
 NumPy was
 :info:configure installed.
 :info:configure We have compiled some common reasons and troubleshooting
 tips at:
 :info:configure     https://numpy.org/devdocs/user/troubleshooting-
 importerror.html
 :info:configure Please note and check the following:
 :info:configure   * The Python version is: Python3.9 from
 "/opt/local/bin/python3.9"
 :info:configure   * The NumPy version is: "1.20.2"
 :info:configure and make sure that they are the versions you expect.
 :info:configure Please carefully study the documentation linked above for
 further help.
