I would recommend using the pyodide xbuildenv install-emscripten command that we have started shipping in recent pyodide-build verions. The benefit is that it's pinned to a specific Emscripten version based on the Pyodide ABI, so you don't need to update it in various places. Another reason is that we apply a number of patches as listed here: https://github.com/pyodide/pyodide/tree/717db5e24fc6602393d194bdcd396554aa4fa90f/emsdk/patches. Some of these have been relevant for Rust extensions for our 2025 ABI and I believe 2026 ABI too.
