title: Don't know how to build rake db:migrate on Ubuntu natty?
body: <p>I'm not sure how to deploy an application using Capistrano but I figured I'd try to at least load all the files I need on my deployment server, so I did a git pull on Github and installed all the dependencies using bundle install. I have RVM 1.6.32 running in Ruby 1.9.2p180 with Rails 3.0.9 and when I run rake db:migrate, I get </p>
  
  <p><code>rake aborted!
  Don't know how to build task 'db:migrate'</code></p>
  
  <p>I don't have the double semi-colon issue that other SO users have mentioned, so I'm genuinely confused. I have rake both 0.9.2 and 0.8.7 installed, as well as bundler 1.0.17. My rvm instance shows 
  <code>rake (0.8.7 ruby)</code></p>
  
  <p>What's going wrong?</p>
