I have just installed SuSE 11.1. When I try to start Apache 2 from the command line I get the following:

Starting httpd2 (prefork) Syntax error on line 2 of /etc/apache2/conf.d/mod_security2.conf:
Invalid command 'SecRuleEngine', perhaps misspelled or defined by a module not included in the server configuration

When I try to install it using YAST I get the following

Cannot adjust 'Apache2' service

I have narrowed it down to ModSecurity. I have reinstalled all the Apache 2 apps and all the required libraries and modules. No luck. Is it something I am doing? Any help and advice you can offer would be greatly appreciated.

Thanks,
