Building snakemake --with bootstrap, with Python 3.15, with the following modification:

+PATH="${PATH-}:%{buildroot}%{_bindir}" \
+    PYTHONPATH='%{buildroot}%{python3_sitelib}' \
+    snakemake --help
 PATH="${PATH-}:%{buildroot}%{_bindir}" \
     PYTHONPATH='%{buildroot}%{python3_sitelib}' \
     help2man --no-info --name='%{summary}' snakemake \

Fails with:

  File "/usr/lib64/python3.15/argparse.py", line 2880, in print_help
    help_text = self.format_help(formatter=formatter)

TypeError: ArgumentParser.format_help() got an unexpected keyword argument 'formatter'


During handling of the above exception, another exception occurred:

I am now also attempting to build it this way in https://copr.fedorainfracloud.org/coprs/g/python/python3.15/package/snakemake/ and https://copr.fedorainfracloud.org/coprs/g/python/python3.15-b1/package/snakemake/


Note that without the modification, the failure is cryptic:

+ help2man --no-info '--name=Metapackage for snakemake: reports extras' snakemake
help2man: can't get `--help' info from snakemake
Try `--no-discard-stderr' if option outputs to stderr


Also note that the log is full of:

Error in import line from /usr/lib/python3.15/site-packages/google_cloud_core-2.3.3-py3.15-nspkg.pth: import sys, types, os;p = os.path.join(sys._getframe(1).f_locals['sitedir'], *('google',));importlib = __import__('importlib.util');__import__('importlib.machinery');m = sys.modules.setdefault('google', importlib.util.module_from_spec(importlib.machinery.PathFinder.find_spec('google', [os.path.dirname(p)])));m = m or sys.modules.setdefault('google', types.ModuleType('google'));mp = (m or []) and m.__dict__.setdefault('__path__',[]);(p not in mp) and mp.append(p)
  Traceback (most recent call last):
    File "<frozen site>", line 319, in _exec_imports
    File "<string>", line 1, in <module>
  KeyError: "local variable ''sitedir'' is not defined"

This is not relevant to this failure, and such errors are safe to ignore (for now).
