title: Rails 3.0.3 - Oracle_enhanced doesn't work
body: <p>I have been using Ruby 1.8 + Rails 2.3.5 with oracle_enhanced and it works fine.</p>
  
  <p>Now I recently installed Ruby 1.9.2 and Rails 3.0.3 on another folder, and I can't get it to work.</p>
  
  <p>When I create a simple application and access it, the page returns the following error:</p>
  
  <blockquote>
    <p>Please install the oracle_enhanced
    adapter: <code>gem install
    activerecord-oracle_enhanced-adapter</code>
    (no such file to load --
    active_record/connection_adapters/oracle_enhanced_adapter)</p>
  </blockquote>
  
  <p>I tried to investigate the problem and found the folder Ruby is using, which is C:\Ruby192\lib\ruby\gems\1.9.1\gems\activerecord-3.0.3\lib\active_record\connection_adapters. In that folder there is no oracle_enhanced_adapter.br file.</p>
  
  <p>The file is in another folder, C:\Ruby192\lib\ruby\gems\1.9.1\gems\activerecord-oracle_enhanced-adapter-1.3.1\lib\active_record\connection_adapters. I tried to copy all rb files from this folder to the other one, I still got an error but it changed:</p>
  
  <blockquote>
    <p>Please install the oracle_enhanced
    adapter: <code>gem install
    activerecord-oracle_enhanced-adapter</code>
    (ERROR: ActiveRecord oracle_enhanced
    adapter could not load ruby-oci8
    library. Please install ruby-oci8
    gem.)</p>
  </blockquote>
  
  <p>I noticed that my old Ruby install (1.8) has the same file/folder structure, and oracle_enhanced works.</p>
  
  <p>If I test the connection manually on IRB it works fine, the problem is only with Rails.</p>
  
  <p>Does anyone have a clue?</p>
  
  <p>I'm using Webrick for now, and my gem list is as follows:</p>
