Import problem with PyCrypto in Jython

Question

I'm currently trying to run the python bittorrent tracker inside jython, and I ran into this problem: the tracker uses the PyCrypto library, which I compiled for my platform and added python to the path. However, when I try to run the code, I get the following error:

Exception in thread "MainThread" Traceback (most recent call last):
  File "./python_dep/BitTorrent-5.2.2/bittorrent-tracker.py", line 21, in <module>
    from BitTorrent.track import track

    from Crypto.Cipher import ARC4
ImportError: cannot import name ARC4
Java Result: 1

I am sure the library is in the python path because the command

import Crypto.Cipher

works well

from Crypto.Cipher import ARC4

no. The java code that I run looks like this:

package jythTest;

import org.python.util.PythonInterpreter;

public class Main {

    public static void main(String[] args) {
         PythonInterpreter pythonInterpreter = new PythonInterpreter();
         pythonInterpreter.exec("import sys");


         pythonInterpreter.exec("sys.path.append(\"./python_dep/BitTorrent-5.2.2/\")");
         pythonInterpreter.exec("sys.path.append(\"./python_dep/Twisted-10.0.0/\")");
         pythonInterpreter.exec("sys.path.append(\"./python_dep/Zope-3.4.0/build/lib.linux-i686-2.6\")");
         pythonInterpreter.exec("sys.path.append(\"./python_dep\")");
         pythonInterpreter.exec("sys.path.append(\"./python_dep/pycrypto-2.0.1/build/lib.linux-i686-2.6\")");
         pythonInterpreter.exec("sys.path.append(\"import Crypto.Cipher\")");

         //pythonInterpreter.exec("print sys.path");
         pythonInterpreter.execfile("./python_dep/BitTorrent-5.2.2/bittorrent-tracker.py");
    }
}

Thanks in advance to anyone who could provide any assistance.
