Rails start problem

Hi!

I’ve installed ruby(1.8.4)/rails(1.1.6) at Centos, and when I try to
execute “rails -v” command - get strange error:

/usr/local/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/core_ext/module/introspection.rb:6:in

I.e. problem with require rails gem.

Thanks,
