I am installing cartoDB in ubuntu using this procedure . When I initialize the metadatabase using the following command

RAILS_ENV=development bundle exec rake db:create

I get an error saying

What could be the problem. I am not conversant with RoR.

Find the Gemfile and add the following line (just below line 35 gem 'net-ldap', '0.11' )

gem install 'net-telnet'

run

$ bundle
