Its normal this warning in Rails 4 install on Ubuntu 12.04 x64?

Question

When I execute this command:

➜  ~  gem install rails

I get a lot warnings: Rails 4.0 warnings

It's normal? (I'm starting now with Rails, so... I'm "newbie")

Looks like an RDoc bug --> https://github.com/rdoc/rdoc/issues/189

Try updating RDoc: gem install rdoc

Alternatively, you can skip installing the documentation, since it's available online:

gem install rails --no-ri --no-rdoc
