Hi!

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

We found that the necessary fixes have recently been applied in the
upstream repository [2].

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

Happy hacking,
