License Classifier problem on Raspberry Pi OS/Debian Trixie

I'm getting this failure when trying to install on a fresh build of Raspberry Pi OS, which to my surprise is now Debian Trixie. Looks like it was released only 10 days ago, so I am going to roll back to Bookworm and revisit when there's been time for the developers to even react to the new release. :)

This is the full output of the command:

Let me know if you'd like me to post the same on the AHTx0 repo as well. I tried installing each package separately and got the same results for INA219 and AHTx0.

Start by reproducing the pip install failure on Raspberry Pi OS/Debian 13 with Python 3.13, focusing on the sysv_ipc build output and missing Python.h. Check the project's installation guidance and dependency requirements; done means establishing whether INA219 installs successfully on the reported platform or documenting the required project change.
