Kudos to Ben and the rest of the Captcha team.
Today I downloaded the binaries for reCaptcha.NET for a web page that I was setting up and it worked out of the box. No recompiles necessary:
<recaptcha:RecaptchaControl ID="recaptcha" runat="server" Theme="red" PublicKey="YourKey" PrivateKey="YourOtherKey"/>
