Steps:

git clone -v https://github.com/bazel-contrib/rules_python.git
git reset d31ec0d92d3c45d8898be5228b88f3c29f6a6eee --hard
export USE_BAZEL_VERSION=24ec866bc2c0761a7ceba400ad07f484841ff9a2
bazel build -- ... @rules_python//examples/wheel/...

Reproduce the failure with the provided repository reset, USE_BAZEL_VERSION, and bazel build command. Start with tests/toolchains/transitions:test_minor_versions and its referenced test logs, then compare the Linux and Darwin paths involved in toolchain resolution. Done means the test passes on macOS without the reported path mismatch.
