Why does httpd fail to load mod_ssl.so with error "Cannot load /etc/httpd/modules/mod_ssl.so into server: libssl.so.10: cannot open shared object file: No such file or directory"

Issue

Why does httpd fail to start and throws the following error message:

Starting httpd: httpd: Syntax error on line 1011 of /etc/httpd/conf/httpd.conf: Syntax error on line 24 of /opt/smarts-ncm/conf/httpd.conf: Cannot load /etc/httpd/modules/mod_ssl.so into server: libssl.so.10: cannot open shared object file: No such file or directory
