Notes for python-xlrd - reproducible builds result

Version annotated: 0.9.2-1
Identified issues:
Identifier: python_shebang_and_dependency_nondeterministically_3_or_3_point_5
Description The initial line of python programs is #!/usr/bin/python3.5 in build1 and #!/usr/bin/python3 in build2.
This is caused by us building multiple Python versions into separate
directories under {build_dir} but then installing them to the *same*
If any of these builds complete in under 1 second, distutils may decide to
skip copying files to {destdir} as it incorrectly believes them to be
up-to-date. This will result in a package arbitrarily containing scripts
with different version shebangs and, by extension, binary dependencies.
Comments: Non-deterministically selects python vs python3.X in shebang

Our notes about issues affecting packages are stored in notes.git and are targeted at packages in Debian in 'unstable/amd64' (unless they say otherwise).
