title: Dojo build 1.7 built packages does not work
body: <p>I'm at the beginning of building my project and I get some errors that couldn't realize why they are being occured. </p>
  
  <p>You can see contents of <code>my app.profile.js</code> file below. I execute 
  <code>"build profile=../../app.profile.js -r"</code> this line from command prompt and I get no error after the process is done. My problem is if I copy the release(built) version of these packages to the place where the unbuilt versions exist, I get too many javascript errors like "<code>Error: multipleDefine</code>". Even if I copy only dojo, dojox and dijit folders, same errors are keep occuring. </p>

  <pre><code>//built 
  define("dojo/Deferred", [ 
          "./_base/lang", 
          "./promise/CancelError", 
          "./promise/Promise" 
  ], function( 
  </code></pre>

  <pre><code>define([ 
          "./_base/lang", 
          "./promise/CancelError", 
          "./promise/Promise" 
  ], function( 
  </code></pre>
  
  <p>So I'm a little bit stucked at the beginning. I want to try using layers to reduce http requests as soon as possible but I need some help about the situation I mentioned. Any help will be greatly appreciated, thanks. </p>
