Build fails with python3.13

[cursedgrape]

Please provide the following information

libtorrent version (or branch): RC_2_0

platform/architecture: macOS Monterey, 12.7.6

compiler and compiler version: clang 14.0.0

please describe what symptom you see, what you would expect to see instead and
how to reproduce it.

When I run python3.12 setup.py build, it works just fine. If I use 3.13 instead, I get the error below:

The python version you're building against must match the version boost_python was built against. If you use a pre-built boost_python (say, from homebrew), you must make sure to use the same python version as it used.

Yeah, I fixed the issue by building boost against python3.13 and this fixed the issue, thanks. Are you planning to update pypi to support 3.13?
