title: No PyPDF2 module found after MacPorts installation
body: <p>I tried to install the <code>module PyPDF2 (version 1.26.0)</code> with MacPorts via
  <code>sudo port install py-pypdf2</code> on High Sierra. I also tried <code>+universal</code> variant.
  Additionally, due to dependencies, the port <code>py310-pypdf2</code> has also been added successfully.</p>
  <p>Checking installed ports results in <code>py-pypdf2 @1.26.0_0 (active)</code> and can be found in
  <code>/opt/local/var/macports/software/py-pypdf2</code> (similarly <code>py310-pypdf2</code>)</p>
  <p>Why does python not find this module?</p>
  <pre><code>Python 3.9.9 (main, Nov 16 2021, 07:16:27) 
  [Clang 9.1.0 (clang-902.0.39.2)] on darwin
  
  &gt;&gt;&gt; import PyPDF2
  Traceback (most recent call last):
    File &quot;&lt;stdin&gt;&quot;, line 1, in &lt;module&gt;
  ModuleNotFoundError: No module named 'PyPDF2'
  
  &gt;&gt;&gt; help('modules pypdf2')  -&gt; returns nothing
