        from <internal:lib/rubygems/custom_require>:29:in `require'

nds/app.rb:1:in `<top (required)>'
        from <internal:lib/rubygems/custom_require>:29:in `require'
        from <internal:lib/rubygems/custom_require>:29:in `require'

nd.rb:5:in `block in <top (required)>'
        from /usr/local/lib/ruby/gems/1.9.1/gems/heroku-1.10.14/lib/heroku/comma

I'm running Windows Vista using Cygwin. I have installed ruby-1.9.2-p0 and Rails 3.0.0.

The Ruby you are using wasn't compiled against the 'readline' library. Compiling ruby with readline support on Windows involves getting a copy of Visual Studio and compiling a lot of stuff with your bare hands.

Normally I'd recommend you use rvm, but rvm doesn't support windows for exactly the reason I just mentioned.

My recommendation would be to develop on a Linux machine or a Mac. Having a Unix environment about is a must for any serious developer.

If you're really attached to your Windows, here's a guide on installing Ruby 1.9 on Windows, including readline, but I don't know if it'll solve the issue you're currently having.
