I just install rails 3 and all gems that it need, but when I try to start server, it says about problem in boot script.

[rap-kasta@acerAspire testR3]$ script/rails server  
/home/rap-kasta/tmp/testR3/config/boot.rb:7:in `rescue in <top (required)>': uninitialized constant Bundler (NameError)  
        from /home/rap-kasta/tmp/testR3/config/boot.rb:2:in `<top (required)>'  
        from script/rails:9:in `require'  
        from script/rails:9:in `<main>  

So, I tried to reinstall Bundler, install "pre"-version (but really it has version number lower then i install by gem install bundler
