A further symptom on this issue. When I execute irb I detect the
following:
===
C:\Ruby\bin> irb
irb(main):001:0>  require 'rubygems'
=>  true
irb(main):002:0>  require 'sqlite3'
LoadError: 127: The specified procedure could not be found.   -
Init_sqlite3
./sqlite3.dll
        from ./sqlite3.dll
        from C:/Ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:
31:in `require'
        from (irb):2
irb(main):003:0> 
===

Is this saying there is something wrong with the downloaded sqlite3
DLL itself?
