Package archive misses permissions
The distribution available on PyPI have all files permissions set to 600 and directories to 700.
Distributions patch this themselves when packaging python-dateutil:
Modern installers normalize permissions (pip does) but easy_install or setup.py install doesn't. Meaning tools relying on easy_install or setup.py (such as FPM) may end up with insufficient permissions to run the code as a non-root user.
Would it be possible to have the correct permissions in the tarball directly? Adding a+r and g+r seems reasonable.
