To finish the install of mod_gzip-1.3.26.1ap3, you need
to enable the module using the following command

  /usr/local/sbin/mod_gzip-enable

Also, copy the following file into your Apache config:
/usr/local/share/examples/mod_gzip/mod_gzip.conf.sample

The manual is found at /usr/local/share/doc/mod_gzip

If you already have Apache running on your machine,
you should not use "apachectl restart" - instead,
you should fully stop and then start the server.
