[pycrypto] ImportError: cannot import name _counter

[Parthy Chandrasekaran]

Hi,

I need to install pycryto module to use another module (paramiko).
I've installed pycrypto 2.5 for Python 2.7 on Windows XP as follows:

C:\Tools\python\pycrypto-2.5.tar\dist\pycrypto-2.5\pycrypto-2.5>python
setup.py install --install-platbase win32
running install
running build
running build_py
running build_ext
warning: GMP or MPIR library not found; Not building Crypto.PublicKey._fastmath.

When I run the self-test for counter, I get an ImportError for _counter:

C:\Tools\python\pycrypto-2.5.tar\dist\pycrypto-2.5\pycrypto-2.5\lib\Crypto\SelfTest\Util>python
test_Counter.py

  File "test_Counter.py", line 39, in setUp
    from Crypto.Util import Counter
  File "C:\Tools\python\Python27\lib\Crypto\Util\Counter.py", line30,
in <module>
    from Crypto.Util import _counter
ImportError: cannot import name _counter

Any ideas on how I can resolve this import error?

thanks
