Installation borked after installing llm-gpt4all

Background / context

• was originally following install instructions for Mac at https://simonwillison.net/2023/Aug/1/llama-2-mac/ - yeah, I should have spotted that this was an older post....but I didn't
• Macbook Pro on Intel silicon, Sonoma 14.6.1
• Python 3.12.5
• Relative noob to Python and not a Dev for 25 years: it has been a few weeks of hacking with Claude-Dev so this could be "user error"

What I did

1. Installed llm via Homebrew - brew install llm
2. Installed the llm-llama-cpp plugin - llm install llm-llama-cpp
3. Installed the python bindings - llm install llama-cpp-python
4. Ran the test of models installed - llm models (success: got 11 listed, all OpenAI)
5. Instead of downloading a specific model, I opted to install the plugins llm install llm-gpt4all (I didn't do this in a virtual Env btw, just at the command line in terminal)

Among other things I got this from the terminal:

Successfully installed charset-normalizer-3.3.2 gpt4all-2.8.2 llm-gpt4all-0.4 requests-2.32.3 urllib3-2.2.2

6. Ran the test of models installed AGAIN - llm models (but this time got the error below)

No llm related commands seem to work e.g. llm --help (I always get some tracback error)
Next will be try and uninstall llm via HomeBrew.....but I've not gone there yet. No idea if that will work anyway. And I wanted to see if the community here could help first. :)

Reproduce the failure with the Homebrew installation on Intel macOS and Python 3.12. Start at llm/plugins.py, then follow the llm_gpt4all.py and gpt4all import paths shown in the traceback. Done means installing llm-gpt4all no longer prevents commands such as llm models and llm --help from running.
