Ruby on Rails

My current ruby version is ruby 2.0.0p247 (2013-06-27 revision 41674) [x86_64-darwin13.0.0] and rails version is 4.0.0

Every time I run any rails command I get following message first:

    /Users/aniruddhabarapatre1/.rvm/gems/ruby-2.0.0-p247@global/gems/bundler- 1.3.5/lib/bundler/runtime.rb:216: warning: Insecure world writable dir /usr/local in PATH, mode 040777

I was able to create new rails app, but when I start the server using

    rails server or rails s

I get following message ---

I'm stuck on this since last 2 days and would greatly appreciate any help. Just want to start with Rails and create some apps.
But this initial setup is frustrating.
