After installing Instant Rails on one of my machines I then set to install Sqlite, an extremely simple to use database program, and the connector to link it to Ruby. Simple enough, I thought, there's a Gem for it right there. While it was simple to install, there was a little problem with it that it took me a moment to realize what was going on. During the install it said the following:

D:\InstantRails\rails_apps>gem install sqlite3-ruby
Attempting local installation of 'sqlite3-ruby'
Local gem file not found: sqlite3-ruby*.gem
Attempting remote installation of 'sqlite3-ruby'
Updating Gem source index for: http://gems.rubyforge.org
Successfully installed sqlite3-ruby-1.1.0-mswin32
Installing RDoc documentation for sqlite3-ruby-1.1.0-mswin32...
lib/sqlite3/database.rb:637:65: Skipping require of dynamic string: "sqlite3/driver/#{driver.to_s.downcase}/driver"
lib/sqlite3/database.rb:642:59: Skipping require of dynamic string: "sqlite3/driver/#{d.downcase}/driver"

As it turned out the errors listed ("skipping require of..") turns out to be not too serious. As you can see above those lines it has said that the basic install succeeded ok, where it got stuck was automatically generating the documentation, which really isn't a big deal for Rails usage as we won't be hitting the Sqlite functions directly.
