error starting httpd in new Fedora 13 install

Hi, I have a new Fedora 13 install and with it Apache 2.2, config'd the httpd.conf with the basics, but httpd won't start:

Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(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

...anyone seen this? - thx

 

What does this command return:

lsof -i :80

 

Nothing, just returns to the command prompt - so should be no other app/daemon at port 80 yet this error...strange...let me know if you have any other ideas and thanks!
