[pycrypto] Install failure

[Dean Macinskas]

Platform: W7pro, 64-bit

I downloaded the latest version (2.3) and ran "python setup.py install".  Here's what I see:

C:\Users\dmacinskas\AppData\Local\Temp\pycrypto\pycrypto-2.3>python setup.py install
running install
running build
running build_py
running build_ext
warning: GMP library not found; Not building Crypto.PublicKey._fastmath.
building 'Crypto.Random.OSRNG.winrandom' extension
error: Unable to find vcvarsall.bat

C:\Users\dmacinskas\AppData\Local\Temp\pycrypto\pycrypto-2.3>

This appears to defeat the install, because subsequently importing Crypto.Cipher produces a "module not found" error.

Any advice?

Thanks,
dpm
