    You must manually edit #{apache_configdir}/httpd.conf to include
      LoadModule wsgi_module #{libexec}/mod_wsgi.so

    NOTE: If you're _NOT_ using --with-brewed-httpd22 or --with-brewed-httpd24 and having
    installation problems relating to a missing `cc` compiler and `OSX#{MACOS_VERSION}.xctoolchain`,
