Unable to install python 3.13 on Sequoia

My normally faultless brew install of python 3.x has encountered an issue with 3.13. I'd appreciate any pointers. I've tried removing brew, plus all formulae before reinstalling brew and [python@3.13](mailto:python@3.13). Here's the on screen errors after the auto installation of the dependancies.
