uninitialized constant Rake::DSL

So I was restless over the weekend and I decided to install the entire ruby/rails environment on my computer. I followed the process at the link below but I got stuck on the "verify heroku is setup" step. Here's the output from the command prompt. Can you help? I was super excited that I got that far. Basically, it seems like I created a database but I can't migrate it to the test app I created. I'm wondering if it had anything to do with the fact that I had heroku on here before I started downloading all the other stuff. I tried to revert my rake to 0.8.7 but that didnt help either. Let me know your thoughts.

    This one was buried in our spam filter, just unearthed it. Sorry.

    I would definitely try the latest version of the RailsInstaller and see if it's fixed. If not, we can point you to the folks at EngineYard that made that project so they can help you.
