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:

root@kuliksco-ub:/u1/app/wldev# script/server  
=\> Booting WEBrick…

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

Best regards,

```
