What steps will reproduce the problem?

pip install -d pyodbc

python2.7 setup.py bdist_rpm --spec-only

grep Source0 pyodbc-3.0.7/dist/pyodbc.spec

Source0: pyodbc-%{unmangled_version}.tar.gz

What is the expected output? What do you see instead?

the source must match the original package, in this case pip downloads a zip file but then setuptools looks for a tar.gz. I think setuptools does not support zip files. Perhaps uploading a tar.gz version to pypi would solve the problem

What version of the product are you using? On what operating system?

pyodbc 3.0.7 Centos 6.4
