Can you be more specific?

the gem is sqlite3-ruby:
sqlite3-ruby (1.2.1)

The latest One-Click Installer version:
ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]

RubyGems version installed:
0.9.4

(Also tested on 1.0.1)

Output from IRB:

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'sqlite3'
=> true
irb(main):003:0> db = SQLite3::Database.new("test.db3")
=> #<SQLite3::Database:0x516f198 ...>

Now, using ruby command line:

D:\Users\Luis\Desktop>ruby test-sqlite3.rb

No output for your script

and with -v (Verbose mode):
D:\Users\Luis\Desktop>ruby -v test-sqlite3.rb
ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32]
C:/Ruby/lib/ruby/gems/1.8/gems/sqlite3-ruby-1.2.1-x86-mswin32/lib/
sqlite3_api.so: warning: global variable `
$swig_runtime_data_type_pointer2' not initialized

Conclusion:
The warning you're getting is because:
You used -v command line option to run your script or
You tweaked $VERBOSE and set it to true

HTH,
