Hi!

While rebuilding the python related packages against the Python 3.15rc2
version we found that python-bytecode fails to build from source [1].

The problem can be solved with upstream commit
4bff24f022bb2c6bfe1c368821180534140ce0bb: feat: add support for CPython
3.15 [2].

I've applied the upstream fix in the sandbox [3] to verify that it
builds successfully, please consider applying the patch to support the
upcoming 3.15 version.

Setting the severity to important for now. Once Python 3.15 is released,
it will be added to python3-defaults and this bug will become release
critical.

Happy hacking,
