You'll either need to install the package "python3-crypto" or compile
it yourself.

To build it locally, you'll need to setup your build environment. The
packages build-essential, python3-dev, python3-setuptools, and
libgmp-dev should suffice. Once everything is setup, simply run the
following:

    sudo easy_install3 --verbose pycrypto

On My Debian system it installs to
/usr/local/lib/python3.2/dist-packages/. You can also run the self
tests:

    >>> import sys
    >>> import Crypto.SelfTest
    >>> Crypto.SelfTest.run(verbosity=1, stream=sys.stdout)

For me it ran 1078 tests (one dot per test).
