Help with enabling SNI on RHEL 5.9 (Tikanga), please...

Hello:
A web developer customer of ours requested the following:
"We'd like to request that SNI be enabled on our WordPress servers so that
they can use both wildcard security certificates:
Reference:
https://www.digicert.com/ssl-support/apache-multiple-ssl-certificates-using-sni.htm
"
SNI requires:
1). OpenSSL v0.9.8j
2). Apache v2.2.12

I am providing the commands I used and the results of those commands, further below, to identify the environment, in order to see if we can enable SNI, and if so, what are the steps (as being a newbie to this stuff).

I did find the following but not quite sure:
URL: https://access.redhat.com/solutions/28044
Information from that web page:
"
SNI is supported in Apache 2.2.12 or later using mod_ssl (http://wiki.apache.org/httpd/NameBasedSSLVHostsWithSNI)
This is supported in RHEL 6 (httpd-2.2.15-5.el6) but not in RHEL 5 (httpd-2.2.3.el5) - https://rhn.redhat.com/rhn/software/packages/details/Overview.do?pid=422047
"
Thank you!
