apache does'nt start

i have installed apache server and when i try to start it i get the message :

./apache2ctl start
httpd2: Syntax error on line 193 of /etc/apache2/httpd.conf: Could not open configuration file /etc/apache2/sysconfig.d/include.conf: No such file or directory

i have no include.conf file but i don’t know what to put in it!
Thanks for your help
