Rails 3.0pre Appears To Be Broken

I have been trying to run the latest Edge Rails (i.e. Rails 3.0pre) appear to be broken and I haven't been able to get it to run for several days now. At this time, I'm getting the following error message:

$ script/server
/Users/conradwt/rails.dir/examples/blog/config/boot.rb:45:in `require': no such file to load -- /Users/conradwt/rails.dir/examples/blog/config/../vendor/rails/railties/lib/initializer (LoadError)
    from /Users/conradwt/rails.dir/examples/blog/config/boot.rb:45:in `load_initializer'
    from /Users/conradwt/rails.dir/examples/blog/config/boot.rb:38:in `run'
    from /Users/conradwt/rails.dir/examples/blog/config/boot.rb:11:in `boot!'
    from /Users/conradwt/rails.dir/examples/blog/config/boot.rb:110:in `<top (required)>'
    from script/server:2:in `require'
    from script/server:2:in `<main>'

Lastly, I have tried this in Ruby 1.9.1 using Mac OS 10.6.1.
