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:

RPM build errors:
error: Bad exit status from /var/tmp/rpm-tmp.7sHWCS (%generate_buildrequires)
    Bad exit status from /var/tmp/rpm-tmp.7sHWCS (%generate_buildrequires)]: [The is a bad exit status code from cython]
=============
[Requirement satisfied: cython>=0.29.24; platform_python_implementation == 'CPython'
   (installed: cython 3.0.12)]: [cython seems installed and available]


Answer: Issue: python-sqlalchemy requires cython for performance, since cython returns a bad exit code the build fails
Resolution: Investigate why there is a bad exit code from cython
