I setup ruby and mysql on my mac and i am having issues connecting to my local mysql server.

require 'rubygems'
require 'mysql'
...    
db = Mysql.new("localhost", "root", "", "")
...

This would give me the following error when i run this script fromt he command line:

generate.rb:37:in `initialize': wrong number of arguments (4 for 0) (ArgumentError)
from generate.rb:37:in `new'
from generate.rb:37

I have no idea why i am getting this error…any ideas?
