problem upgrading apache-ssl package

[Pollywog <pollywog@shadypond.com>]

I ran apt-get on potato and I got this, after upgrading apache-ssl:
/etc/apache-ssl/apache.pem exists!  Use "/usr/sbin/ssl-certificate --force."

I then ran the command, as told to do above:

lilypad:/home/pollywog#/usr/sbin/ssl-certificate --force

And I got this:

creating selfsingned certificate
replace it with one signed by a certification authority (CA)

enter your ServerName at the Common Name prompt

If you want your certificate to expire after x days call this programm
with -days x
/usr/sbin/ssl-certificate: openssl: command not found
lilypad:/home/pollywog#/usr/sbin/ssl-certificate --force

What is wrong here?  Anyone else have the same problem?
