Thanks Tom. Found out the problem is GoDaddy didn't install GhostScript
as Robby's post has suggested. I ended up using recaptcha and a ruby
plugin to talk to recaptcha server. It was simple enough and it only
takes me less than an hour to implement. Also the added bonus is
recaptcha also support audio, not just visual images. I thought that is
pretty cool.
