[TriLUG] Apache2 SSL

I have a SLES 9 box running Apache 2.0.54 happily. However, I would like to setup SSL an be able to access pages on the box using https://. Easy enough I thought. I looked in the listen.conf file and saw the following:

Listen 80

<IfDefine SSL>
    <IfDefine !NOSSL>
        <IfModule mod_ssl.c>
            Listen 443

This should mean that the server will listen on port 443, however it isn't. If I add a Listen 443 right under the Listen 80 it works. So, that got me wondering what this <ifdefine ssl> does and why it wasn't working. I did the google search and found a couple of things, one which mentioned apache2 should be started with the -DSSL option (as seen in a ps awx | grep http), but I just see the following:

21671 ?        Ss     0:00 /usr/sbin/httpd2-prefork -f /etc/apache2/httpd.conf

So, what do I need to do to get apache2 to start on SLES with SSL support? I know I can just add the Listen 443 option manually, but this has become more of a quest for learning what the <ifdefine ssl> is for and why it isn't working.

Thanks for your help.
