Comments and tracebacks

I'm sure this will be hard to understand, but I am still working on getting comments and tracebacks working. I wrestled with getting Image::Magick installed; no luck. Then I worked on getting reCaptcha installed just so I could have some captcha provider in my list. That was impeded by my FTP client hanging up, but once I restarted that, it was fine. So now I don't know what the problem is:

• reCaptcha is listed as a plugin
• reCaptcha is selected as my CAPTCHA provider
• Comments are set to Immediate approve comments from: Anyone
• Registration is set to Anonymous comments with Require E-mail Address for Anonymous Comments set
• Web Services setting has a Type Key value obtained from SixApart
• Entire website has been rebuilt
• I've followed all the instructions on Adding reCAPTCHA to Movable Type
  

You'd think it would be fine. So I'll be waiting here for someone to post a comment on how to fix this -- no wait.
