Getting "WARNING (aesara.configdefaults): g++ not available," on fresh PyMC4 install

Hi @nicholasj, thanks for the more detailed report! I’m glad you got things running.

I have been steadily improving the Conda package, and so I have a suspicion that your download of full Anaconda randomly coincided with a change I made.

In case you are motivated to experiment further, I’d be interested to see the output of the conda create... command.
