Obviously, there is already running a process which listens on Port 80. Either find out, if there is already running an Apache (httpd), you can use "top" or "ps -fe" command line tool, or use net tools like "lsof" (use "man lsof" to find out usage) or "netstat" for example to look for ports and processes. You must find the blocking application and probably stop it and/or de-install it.

Do you have "Skype" installed? This also is known for blocking Port 80.
