Hi!

While rebuilding the python related packages against the Python 3.15rc1
version we found that python-mashumaro fails to build from source [1].

This problem has already been fixed upstream with commit da19903 [2].

I've applied the upstream fix in the sandbox [3] to be able to build the
packages that depend on python-mashumaro, please consider applying the
patch to support the upcoming 3.15 version.

Happy hacking,
