title: NuGet: pack command is NOT including nuget dependencies
body: <p>i have the following setting:</p>
  
  <ul>
  <li>nuget.exe Version: 1.6.21205.9031</li>
  <li>Project A.csproj packaged into A.1.0.0.0.nupkg, and published to a LOCAL package repository hosted on my local IIS (My VS Nuget Extension i able to add the A-package to a new project)</li>
  <li>Project B.csproj has a dependency to the A-package that i added with the VS Nuget Extension</li>
  </ul>
  
  <p>Now, when i run</p>
  
  <pre><code>nuget spec
  </code></pre>
  
  <p>the B.nuspec is created.</p>
  
  <p>Then i run</p>
  
  <pre><code>nuget pack B.csproj -verbose
  </code></pre>
  
  <p>but in the created B-package, their is NO dependency to the A-package. The nuget pack command tells me that it has found the packages.config file (which contains the dependency to the A-package), but then it says "Dependencies: None".</p>
  
  <p>What am i missing? Could the problem be that the A-package can only be found in my local package repository? How can i make nuget.exe aware of this local repository?</p>
  
  <p>Thanks a lot!</p>
