I don't know what Sift is really supposed to do/be, but let's assume it's the sift in PyPI. On Windows 8.1:

If this is a Windows 7 problem: note that we really cannot support Windows 7, which saw mainstream end of life earlier this year (January 13, 2015).

I also successfully installed on OS X 10.11.1, both 2.7.0 and 2.7.1
