Apache error


My Apache will not start. If I tell it to start via the terminal I get the following error:

Syntax error on line 207 of /etc/httpd/httpd.conf:
Invalid command 'LoadModule', perhaps mis-spelled or defined by a module not included in the server configuration
/usr/sbin/apachectl start: httpd could not be started

I have compared httpd.conf with the same file on my other computer (on which apache works), and can find no difference.
