Hi y'all,
I'm new here so please be kind to me :-)

I'm using WinXP Pro, One-click installer Window ruby182-14.exe and 
mysql-4.1.10-win32.zip

The code I wrote is : mysql.rb

require 'mysql'

m = Mysql.new("localhost", "ariebanaranakai", "iwakkaring", "budiman")
r = m.query("SELECT username, password FROM user");
r.each_hash do |f|
    print "#{f['username']} . #{f['password']}"
end

The Error I got is :

./mysql.rb:3: uninitialized constant Mysql (NameError)
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in 
'require__'
from c:/ruby/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in 
'require'
from mysql.rb:1

What's the matter with this ? I've searched the archieves but found 
nothing :-(  
I've also asked rubyist mailing list in my country but they averagely 
said they never get the problem like I do  :'(

Please help me and thanks a lot.

Arie
