title: Why is my rubgems not making symbolic links to binaries?
body: <p>I'm on Ubuntu 11.04 with ruby 1.9.2p180 installed from source using rvm. When I install a gem that makes a command-line binary, links are not made. For example, when I install the passenger gem, <code>/var/lib/gems/1.9.2/bin/passenger</code> is installed as expected and works, but a symbolic link is not made from <code>/usr/bin/passenger</code> as expected.</p>
  
  <p><strong>update</strong></p>
  
  <p>actually I have the same problem with vendor ruby and gem (on a different 11.04 server that has never had rvm).</p>
