import zero_buffer fails

I've installed zero buffer from pip on 4 machines.

Windows:

>>> import zero_buffer
_cffi__xc803fa62x9f782fd2.c
C:\Python27\lib\site-packages\__pycache__\_cffi__xc803fa62x9f782fd2.c(188) : fatal error C1083: Cannot open include file: 'sys/uio.h': No such file or directory

Tried cloning from git. python setup.py install works. On windows however I keep having verification errors.
