&gt;     There may be some support for requesting specific versions from<br>
&gt;     Homebrew.<br>
&gt;<br>
&gt;<br>
&gt; Try `brew versions llvm`. Then, you&#39;ll need to run the git checkout<br>
&gt; command in `brew --prefix` directory.<br>
&gt;<br>
<br>
Or brew tap homebrew/versions and then install llvm31 or whatever<br>
