title: MacOS 12.1 cannot find my brew install of GNU binutils
body: <p>I want to use GNU binutils to inspect an executable on MacOS 12.1. I did a</p>
  <pre><code>% brew install binutils
  </code></pre>
  <p>and it seemed to go fine. First I tried just a</p>
  <pre><code>% readelf &lt;executable&gt;
  </code></pre>
  <p>but was given:</p>
  <pre><code>zsh: command not found: readelf
  </code></pre>
  <p>Then I tried checking on binutils itself:</p>
  <pre><code>% binutils -v
  </code></pre>
  <p>which gave me</p>
  <pre><code>zsh: command not found: binutils
  </code></pre>
  <p>I tried adding both</p>
  <pre><code>/usr/local/opt/binutils
  </code></pre>
  <p>and</p>
  <pre><code>/usr/local/Cellar/binutils
  </code></pre>
  <p>to my $PATH and restarting zsh. The filepaths were in my $PATH, and homebrew had put 'binutils' in the expected locations. But</p>
  <pre><code>% binutils -v
  </code></pre>
  <p>still gives me</p>
  <pre><code>zsh: command not found: binutils
  </code></pre>
  <p>.
  Has anyone gotten binutils to work on Mac? What am I missing?</p>
