[Python] Numpy 2.0.2 installation fails on Raspberry pi 4B running OSMC, Python 3.9.2

I'm trying to install numpy 2.0.2 on a Raspberry pi 4B running OSMC and Python 3.9.2.
pip tries to compile numpy locally, and fails. I can't get past this error, and I also failed upgrading Python (hoping a newer Python and numpy will circumvent the issue).
Any suggestions?

Error message:

Run-time dependency python found: NO (tried pkgconfig, pkgconfig and sysconfig)
../meson.build:41:12: ERROR: Python dependency not found


Full log in pastebin

The installation folder that's supposed to contain the meson build log (/tmp/pip-install-ph6xune8) doesn't exist:

cd /tmp/pip-install-ph6xune8/ -bash:
cd: /tmp/pip-install-ph6xune8/: No such file or directory


Setup details:
HW:
Raspberry Pi 4 Model B Rev 1.4
OS:

PRETTY_NAME="Open Source Media Center"
NAME="OSMC"
VERSION="October 2024"
VERSION_ID="2024.10-1"


Python:

pip 25.0.1
Running in a virtual environment

Things I tried:
Updating tools: pip, setuptools, wheel
Updating compilers and dependencies: cc, gcc, software-properties-common, build-essential, pkg-config
Upgrading python so I get a newer version of numpy (failed... apt doesn't accept deadsnakes repo due to security issues, building from source also failed)
