title: Delphi Package: "The following changes must be made..." never goes away
body: <p>On one of my packages, which was adapted from another using Save-As and edit, I keep getting the following message (this is in Delphi 2007):</p>
  
  <p>=======<br>
  The following changes must be made before this package can be compiled. 
  Choose OK to apply these changes and continue compiling.</p>
  
  <pre><code>  Remove cmSizePanel_Reg.  
    Unit(s) cmSizePanel_Reg were found in required package cmExtRzPanel_D2007.
  </code></pre>
  
  <p>=======</p>
  
  <p>I click OK, and it then proceeds to compile fine. This message, however, never goes away -- I get it every time I compile the package.</p>
  
  <p>Here is the project source, using right-click, "View Source" to get there:</p>
  
  <pre><code>package cmBaseFrames_D2007;

    cmExtRzPanel_D2007;
  
  contains
    cmBaseFrames_Reg in 'cmBaseFrames_Reg.pas',
    cmBaseFrameFrame in 'cmBaseFrameFrame.pas' {cmBaseFrame: TFrame},
    cmBaseSizeableFrameFrame in 'cmBaseSizeableFrameFrame.pas' {cmBaseSizeableFrame: TFrame};
  
  end.
  </code></pre>
  
  <p>"cmSizePanel_Reg" isn't in the project anymore, and doesn't show up in teh Project Manager panel.  It would appear that it's "hiding" somewhere in one of the file Delphi uses for the package, but I'm not seeing where.  Any ideas how to stomp out this little inconvenience without having to complete re-create the package from scratch?</p>
