title: Delphi XE6 Component package issue. Can't compile project
body: <p>Using <code>Rewrite</code> I was getting an error</p>
  
  <blockquote>
    <p>E2158 System unit out of date or corrupted: missing '@assign'.</p>
  </blockquote>
  
  <p>So I exited, and renamed my <code>.dproj</code> file.  Once the new <code>.dproj</code> was generated, I tried to compile my project again.  Now I'm getting an error</p>
  
  <blockquote>
    <p>E2202 Required package 'indy' not found.</p>
  </blockquote>
  
  <p>I checked my Indy package and it's installed.  I uninstalled it, and reinstalled, but no change.  If I go into Component->Install Packages... and scroll down to the Indy 10 Core Design Time and/or Indy 10 Protocols Design Time and highlight one, then click the Edit button I get an error</p>
  
  <blockquote>
    <p>Unable to edit package dclindyprotocols200.bpl. The source could not be found.</p>
  </blockquote>
  
  <p>How do I correct this?</p>
