Shutting down http: [ OK ]
Starting httpd:
Syntax error on line 70 of /etc/httpd/conf/httpd.conf:
API module structure `php4_module' in file /etc/httpd/modules/libphp4.so is garble
d - perhaps this is not an Apache module DSO?
[FAILED]

any ideas what this error means?

I got it when i edited my httpd.conf file and went to restart the daemon with php modules active.
