title: "Undefined variable from import" when importing numpy in eclipse pydev
body: <p>I get "Undefined variable from import" error in Eclipse 3.7.2 PyDev 2.7.1 on Linux Mint Maya (Cinnamon) whenever I import a module from numpy. The problem only arises when importing numpy; other modules work just fine.</p>
  
  <p>Info: numpy is compiled against the Intel MKL libraries. Python 2.7.3 [GCC 4.6.3]</p>
  
  <p>example:</p>
  
  <pre><code>import numpy as np
  
  a = np.array([1, 2])
  </code></pre>
  
  <p>Error message in PyDev editor:
  "Undefined variable from import: array"</p>
  
  <p>I get similar errors for other numpy submodules.</p>
  
  <p>The code runs properly either within Eclipse or in a terminal. The problem is only present in the Eclipse-PyDev editor.</p>
