Given following log snippets, their explanation, and nothing else, explain what failure, if any, occurred during build of this package.

  Snippets are in a format of [X] : [Y], where [X] is a log snippet, and [Y] is the explanation.

  Snippets are delimited with '================'.

  Drawing on information from all snippets, provide a concise explanation of the issue and recommend a solution.

  Explanation of the issue, and recommended solution, should take a handful of sentences.

  Snippets:

AttributeError: 'Constant' object has no attribute 's']: [The package is defined via a legacy setup.py script (setuptools tuns self.run_setup() to generate the package metadata). The code in the setup.py tries to access an attribute "s" of the "Constant" object, which is not available, hence AttributeError.]
=============
[error: Bad exit status from /var/tmp/rpm-tmp.xHdfQt (%generate_buildrequires)]: [The phase of generating build requirements failed.]

Issue: Attributes ast.Constant.n and ast.Constant.s were removed from Python 3.14. Because they are no longer available, the setup.py script can't be run successfully.
Resolution: What's new in Python 3.14 suggests to use ast.Constant.value instead of the removed attributes. This should be changed in the setup.py file defining the package metadata.
