title: use 'perl module" not working as not able to add path to module in Epic
body: <p>I have Active state Perl 5.20.2 (32 bit) installed in my Win 7 machine. I am using Eclipse Release (4.5.1) and Epic add-on for Perl.<br>
  <em>I am using PERl,Eclipse and Epic for the first time.</em></p>
  
  <p>I have following structure for workspace and projects:</p>
  
  <blockquote>
    <p>C:\SVN\BuildToolWorkspace        -> workspace path<br>
    C:\SVN\BuildToolWorkspace\BuildToolPerlProj   ->project path<br>
    C:\SVN\BuildToolWorkspace\BuildToolPerlProj\adsp2mk.pl  -> Perl file<br>
    C:\SVN\BuildToolWorkspace\BuildToolPerlProj\adsp2common.pm                                -> Perl module</p>
  </blockquote>
  
  <p>I see red cross in front of main Perl file adsp2mk.pl and the project.
  hovering over the code show following:

  <p>I add the path to Perl include folder/file as
  <a href="https://i.stack.imgur.com/ssYzw.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ssYzw.jpg" alt="enter image description here"></a></p>
  
  <p>As I close project peoperties and open them again, the path is gone and I still have the error for the project and inside the file.</p>
  
  <p><strong>Note/Update</strong>:after reading the comments I did following:</p>
  
  <p><a href="https://i.stack.imgur.com/qgHFy.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/qgHFy.jpg" alt="enter image description here"></a></p>
  
  <p>However, even after refresh, I was still getting error at line 35.
  Closed and opened Eclipse <em>and it is gone.</em>
  However, in the navigator window, I still have Red cross in front of the project and the script as</p>
  
  <p><a href="https://i.stack.imgur.com/uN81g.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/uN81g.jpg" alt="enter image description here"></a></p>
  
  <p>Q1) Is this probably due to some other error picked up by syntax check?
      I don't see any red wavy line inside the script code to suggest that.<br>
  Q2) Why didn't refresh remove the error in line 35 , and I had to exit and reopen eclipse?</p>
