title: rake db:create giving me "... (at master) is not checked out", run bundle install
body: <p>I'm seriously stumped.  I run bundle install successfully:</p>
  
  <pre><code>bundle install
  
  ...
  Using activerecord-oracle_enhanced-adapter (1.4.1) from git://github.com/rsim/oracle-enhanced.git (at master)
  ...
  Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
  </code></pre>
  
  <p>But, when I run rake db:create, I get the following</p>
  
  <pre><code>vagrant@lucid32:/vagrant$ rake db:create
  (in /vagrant)
  git://github.com/rsim/oracle-enhanced.git (at master) is not checked out. Please run `bundle install`
  </code></pre>
  
  <p>Trying this too:</p>
  
  <pre><code>vagrant@lucid32:/vagrant$ bundle exec db:create
  bundler: command not found: db:create
  Install missing gem executables with `bundle install`
  </code></pre>
  
  <p>In my Gemfile:</p>
  
  <pre><code>gem 'activerecord-oracle_enhanced-adapter', '~&gt;1.4.1', :git =&gt; 'git://github.com/rsim/oracle-enhanced.git'
  </code></pre>
  
  <p>This is on Ubuntu, where ruby 1.8.7 was installed.  I'm running 1.9.2p290 w/ rbenv.</p>
