Rails Deployment

I just installed rails on a new development environment running ubuntu
8.04

i have installed gem 1.2.0 and the following ruby packages:

sudo aptitude install ruby1.8-dev ruby1.8 ri1.8 rdoc1.8 irb1.8
libreadline-ruby1.8 libruby1.8 libopenssl-ruby sqlite3
libsqlite3-ruby1.8

i am getting this error when starting thin/webrick:

i got it. i needed to

gem install ruby-debug

Scott,

You should not be requiring  ruby-debug in production environment

unless it is absolutely necessary.

Also you can use:

$ gem -v

To report RubyGems version, and:

$ gem list

To list you currently installed gems
