With removal of distutils in python3.12 from setuptools._distutils.dep_util import newer_group does not seem to work in pegen

Bug report

# Add a code block here, if required

    generated_source_path: str,
    build_dir: Optional[str] = None,

    """Compile the generated source for a parser generator into an extension module.

    The extension module will be generated in the same directory as the provided path
    for the generated source, with the same basename (in addition to extension module
    metadata). For example, for the source mydir/parser.c the generated extension
    in a darwin system with python 3.8 will be mydir/parser.cpython-38-darwin.so.

    If *build_dir* is provided, that path will be used as the temporary build directory
    of distutils (this is useful in case you want to use a temporary directory).

    If *library_dir* is provided, that path will be used as the directory for a
    static library of the common parser sources (this is useful in case you are
    creating multiple extensions).

CPython versions tested on:

3.12
3.14

Operating systems tested on:

macOS

从报告中所示的 compile_c_extension 入口点开始，检查在 Python 3.12 和 3.14 下 setuptools._distutils.dep_util 对 newer_group 的导入。复现 pegen 中的 macOS 失败并确定兼容性问题；当解析器生成器的扩展编译在经过测试的 Python 版本上正常工作时，即视为完成。
