<pre>
    When running lldb tests in the new premerge system on Github Actions, we're seeing some test failures due to a missing/misconfigured zlib:

Doesn't look like it should be too complicated to fix, just wanted to create a bug so I don't lose track of the issue and forget to fix it until I see the failure again.
