title: Cocoapods - Found multiple specifications warning
body: <p>On <code>pod install</code>, I am getting warning like <code>Found multiple specifications for "&lt;Pod Name&gt;"</code></p>
  
  <p>It means that I have multiple <code>Podspecs</code> in this directory <code>~/cocoapods/repo</code></p>
  
  <p>Example Podfile:</p>
  
  <pre class="lang-rb prettyprint-override"><code>source '&lt;Private Podspec&gt;'
  source 'https://github.com/CocoaPods/Specs.git'
  platform :ios, '9.0'
  
  target 'SDKDemo' do
    use_frameworks!    
    pod '&lt;Pod Name&gt;'
  end 
  </code></pre>
  
  <p>My question is that </p>
  
  <ol>
  <li>which Podspec will be used when installing pod. </li>
  <li>If Podspec is taken from <code>&lt;Private Podspec&gt;</code>, How it will work in this case </li>
  </ol>
  
  <pre class="lang-rb prettyprint-override"><code>source 'https://github.com/CocoaPods/Specs.git'
  source '&lt;Private Podspec&gt;'
  </code></pre>
  
  <p>I came to conclusion like order of source will affect deciding the Podspec. But I want to clarify this.</p>
