title: ImageMagick not converting
body: <p>I've just installed a fresh copy of ImageMagick from source onto Snow Leopard 1.6.8 following <a href="http://www.imagemagick.org/script/install-source.php" rel="nofollow">these instructions</a> minus the <code>sudo ldconfig /usr/local/lib</code> command because that doesn't seem to exist on Mac.</p>
  
  <p>Then I added this to my global bash file:</p>
  
  <pre><code>export LD_LIBRARY_PATH=$HOME/local/imagemagick/lib:$LD_LIBRARY_PATH
  </code></pre>
  
  <p>Now when I run <code>which identify</code> I get:</p>
  
  <pre><code>/usr/local/bin/identify
  </code></pre>
  
  <p>And when I run the tests, GIF files remain GIF files:</p>
  
  <pre><code>Simpleton:Desktop pawel$ convert logo.gif logo.png
  Simpleton:Desktop pawel$ file logo.png 
  logo.png: GIF image data, version 89a, 640 x 480
  </code></pre>
  
  <p>And when I want to convert a JPG file I get:</p>
  
  <pre><code>Simpleton:Desktop pawel$ convert clouds.jpg clouds.png
  convert: no decode delegate for this image format `clouds.jpg' @ error/constitute.c/ReadImage/532.
  convert: missing an image filename `clouds.png' @ error/convert.c/ConvertImageCommand/3016.
  </code></pre>
  
  <p>When I run <code>identify -list format</code> then I can't see PNG or JPEG libraries. How do I add these without reinstalling ImageMagick?</p>
