title: Python script cannot access imported package files due to lack of permission
body: <p>We recently installed <code>pykakasi</code> package from Git on Linux server on BigData Cluster. </p>
  
  <p>After installation I tried the test program from "Readme" and received this error.</p>
  
  <p>Error Received: </p>
  
  <blockquote>
  <pre><code>PermissionError: [Errno 13] Permission denied: '/opt/python/python35/lib/python3.5/site-packages/pykakasi/kanwadict3.db/data'
  </code></pre>

  <p>I tried to research all the issues reported on Git. Also, searched this and other forums for possible solution but nothing worked.</p>
  
  <p>Program I was testing:</p>
  
  <pre><code>import pykakasi
  
  text = u"かな漢字交じり文"
  kakasi = pykakasi.kakasi()
  kakasi.setMode("H","a") # Hiragana to ascii, default: no conversion
  kakasi.setMode("K","a") # Katakana to ascii, default: no conversion
  kakasi.setMode("J","a") # Japanese to ascii, default: no conversion
  kakasi.setMode("r","Hepburn") # default: use Hepburn Roman table
  kakasi.setMode("s", True) # add space, default: no separator
  kakasi.setMode("C", True) # capitalize, default: no capitalize
  conv = kakasi.getConverter()
  result = conv.do(text)
  print(result)
  </code></pre>
  
  <p>Expected Output: <code>kana Kanji Majiri Bun</code></p>
  
  <p>Detailed Error:</p>
