Hello everyone, I just installed Rails 3 beta3 and when attempting to  
create anything from the Rails generator I get this error:

Hello Hiroshi, just as I did, you can fix this problem by uncommenting  
the line 6 of your application’s Gemfile. It worked for Ruby  
1.9.1p378. It remains buggy on 1.9.2.

Thanks.

What is line 6 in the Gemfile?  
Is it a particular gem that causes the problem?
