title: Gems not found by 'gem list' when using 'bundle install' for git gems with RVM
body: <p>I'm currently trying to run 'bundle install' to install a git based gem using a Gemfile and consequently use ruby/ other ruby commands without bundler with the latest version of RVM (1.14.3).</p>
  
  <p>I believe the cause of the issue is that bundler is installing the git gem into .rvm/gems/ruby-1.9.3-p194@something/bundler/gems while all other gems are installed into .rvm/gems/ruby-1.9.3-p194@something/gems. As a result, 'bundle list' shows the gem but 'gem list' does not.</p>
  
  <p>Any thoughts here? I'd really prefer not to use bundle to execute everything.</p>
