title: Error when importing geopandas OSError: Could not find lib c or load any of its variants []
body: <p>I'm using Spyder with Anaconda and since MacOS last update (Big Sur 11.0.1), when doing
  <code>import geopandas</code>, I get the following error:</p>
  <pre><code>OSError: Could not find lib c or load any of its variants [].
  </code></pre>
  <p>There are several subjects on the matter (particularly <a href="https://stackoverflow.com/questions/39991765/shapely-oserror-could-not-find-lib-c-or-load-any-of-its-variants">this one</a> and <a href="https://github.com/carsonfarmer/python_geospatial/issues/3" rel="noreferrer">this one</a>), that mainly recommends to reset the environment variable <code>DYLD_FALLBACK_LIBRARY_PATH</code> by putting in the Terminal:</p>
  <pre><code>export DYLD_FALLBACK_LIBRARY_PATH=$(HOME)/lib:/usr/local/lib:/lib:/usr/lib
  </code></pre>
  <p>However, here is what I get:</p>
  <pre><code>-bash: HOME: command not found
  </code></pre>
  <p>A <code>brew</code> or <code>pip</code> install didn't fix the problem either.</p>
  <p>Does anyone have an idea on how I can fix this? Am I suppose to replace <code>$(HOME)</code> by something?</p>
  <p>Many thanks!</p>
