title: How can I install qpdf on Mac 10.8.3?
body: <p>When running <code>R CMD check</code> on packages on a Mac build server, I'm getting a warning</p>
  
  <pre><code>â€˜qpdfâ€™ is needed for checks on size reduction of PDFs
  </code></pre>
  
  <p>I can't seem to get <a href="http://sourceforge.net/projects/qpdf/" rel="noreferrer">qpdf</a> installed and on the system.  I tried installing via the fink package manager, but according to the package database (<a href="http://pdb.finkproject.org/pdb/package.php/qpdf" rel="noreferrer">http://pdb.finkproject.org/pdb/package.php/qpdf</a>), qpdf doesn't seem to have been built since osx 10.6, and I'm on 10.8.3.  </p>
  
  <p>Can anyone point me to qpdf mac install or build instructions?  Or is there a way to disable the warning when checking R packages?</p>
  
  <p>This is somewhat related to the question <a href="https://stackoverflow.com/questions/11738844/qpdf-exe-for-compactpdf">qpdf.exe for compactPDF?</a>, although they were on a windows machine and I'm on a mac.</p>
