Apache restart on Ubuntu - error “could not bind to address 0.0.0.0:80”

I'm a n00b - trying to get apache2 set up on Ubuntu 9.10 (Karmic Koala) on Rackspace Cloud. I have set up/configured OpenSSL and installed Apache, but Apache won't start. I assume its a misconfiguration in my /etc/apache2/sites-available/ssl or /etc/apache2/sites-available/default files)

When I try to restart apache using the command:

sudo /etc/init.d/apache2 restart
I get the following error message:

[error] (EAI 2)Name or service not known: Could not resolve host name *.80 -- ignoring! 
[error] (EAI 2)Name or service not known: Could not resolve host name *.80 -- ignoring! 
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down 

Unable to open logs ...fail!

For my /etc/apache2/sites-available/ssl I have used a virtual host of *:443.

For my /etc/apache2/sites-available/default i have used a virtual host of *:80
