Why does ImageMagick from MacPorts does not work, when imagemagick from Homebrew does
<p>I have fixed my error by installing through <code>Homebrew</code> but I would like to know: why does <code>homebrew</code> work but <code>macports</code> does not??</p>

<p>If I install ImageMagick from MacPorts I get this error even though I can call "<code>convert</code>" from the command line:</p>

<pre><code>Traceback (most recent call last):
  File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  File "/Library/Python/2.7/site-packages/wand/image.py", line 20, in &lt;module&gt;
    from .api import MagickPixelPacket, libc, libmagick, library
  File "/Library/Python/2.7/site-packages/wand/api.py", line 205, in &lt;module&gt;
    'Try to install:\n  ' + msg)
ImportError: MagickWand shared library not found.
You probably had not installed ImageMagick library.
Try to install:
  port install imagemagick
</code></pre>

<p>Which I already did!</p>

<p>If I install via <code>homebrew</code>, I can no longer use "<code>convert</code>" from the command line but it plays well with <code>wand</code> from <code>PIP</code>.  Why is that?</p>
