Please Help with RedHat6.2 and OpenSSL?

Hello,
I am running RedHat 6.2 and have recently installed openSSL, by doing the
follwoing:
./config
make
make test
make install
I then created my key and placed it in under
/etc/httpd/conf/ssl.key/www.lithiumsserver.key and then made the following changes to my Virtual Host (which I don't understand very well) now when I restart httpd I get the following error:

[Thu Jan 18 08:56:19 2001] [notice] SIGHUP received. Attempting to restart Syntax error on line 342 of /etc/httpd/conf/httpd.conf: Invalid command 'SSLCertificateFile', perhaps mis-spelled or defined by a module not included in the server configuration

Here is what the VH section of my httpd.conf file looks like. BTW do I have to have a VirtualHost, what advantages does it give me since I want all connections to this server to be secure? Thanks for your help.

<VirtualHost 24.15.49.48:443>
ServerAdmin shea.ferring@analex.com
DocumentRoot /home/httpd/html/Members
ServerName secureworkgroups
#ErrorLog logs/host.some_domain.com-error_log
#TransferLog logs/host.some_domain.com-access_log
#SSLEngine on
SSLCertificateFile etc/httpd/conf/ssl.key/www.lithiumsserver.crt
SSLCertificateKeyFile etc/httpd/conf/ssl.key/www.lithiumsserver.key
</VirtualHost>

You say you've stuck your key and crt here:
/etc/httpd/conf/ssl.key/www.lithiumsserver.key

But you've told Apache to look for crt and key here:
etc/httpd/conf/ssl.key/www.lithiumsserver.crt
etc/httpd/conf/ssl.key/www.lithiumsserver.key

Are you just missing the root slash before those file locations?
