SSL not available, for no apparent reason

Good Day:

I am running Debian stable, with the included packages.
Apache version 1.3.26; mod-ssl version 2.8.9-2.4.

I am using a self-signed certificate for now, until testing proves successful.

If I use openssl, with the s_client and s_server options, I can make a 
successful connection through the local host.

However, apache, while it serves on port 80, does not appear to be serving SSL 
documents.

Here are the contents of a couple files:

I'm not sure what else to examine here, or what I might have screwed up.
