    <p>I think we answered this for you on IRC the other day, since
      someone came in with exactly this question. I'll answer it again
      here just in case, and that way the answer is here if someone else
      comes long looking for it.</p>
    <p><br>
    </p>
    <p>When you upgrade the operating system, you get a new version of
      Perl with it as well as new versions of a lot of other system
      libraries.  Anything binary that was compiled for Bugzilla would
      need to be re-built in order to work with the new library
      versions.  Typically, this is the Perl modules installed as
      prerequisites for Bugzilla in the `lib/` folder within your
      Bugzilla installation.</p>
    <p><br>
    </p>
    <p>The easy fix is to delete the `lib/` directory, then run
      checksetup.pl and re-install any dependencies it now claims are
      missing.<br>
