Apache Update Problem


i tried to upgrade to apache_1.3.19, the installation said everything was installed successfully. but when i tried to start up Apache, got this error

"Syntax error on line 209 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"

the 'LoadModule' it is referring to is "config_log_module " which is located "libexec/httpd/mod_log_config.so"
can anyone tell me what i did wrong....and more importantly how can i fix it
the problem was fixed by editing the /etc/httpd/httpd.conf file to read ServerRoot "/Library/WebServer" instead of ServerRoot "/usr"
