Getting reCaptcha for django

How I got it to work, in another blog

Things that didn't work:
http://seeknuance.com/2008/03/18/integrating-recaptcha-with-django/

(I tried the other option of http://stackoverflow.com/questions/2275806/easy-to-use-django-captcha-or-registration-app-with-captcha/2275996#2275996  and installed django-registration, but I get a error: "ImportError at /msw/register No module named backends.default")
