[pycrypto] chmod error in Windows 7, when trying to install

[Mike Anderson]

I'm using Windows 7 Ultimate, and trying to install pycrypto, but
getting an error "'chmod' is not recognized as an internal or external
command."

It happens like so:
> pip install ssh
   ...
copying lib\Crypto\Signature\__init__.py -> build\lib.win32-2.7\Crypto\Signature


running build_ext

running build_configure

'chmod' is not recognized as an internal or external command,

operable program or batch file.
