Error compiling mod_security

Oh men! Compiling mod_security is hell! I've been trying to compile it for several days now. I successfully compile mod_evasive with a slight issue. Here is my error in mod_security

[root@ip-10-162-54-86 modsecurity-apache_2.6.7]# /usr/local/apache2/bin/apxs -cia apache2/modsecurity.c

There has been an issue with apxs. Upon searching in Google, solution was compile it this way

/usr/local/apache2/bin/apxs -cia -n modsecurity -I /usr/include/libxml2 apache2/modsecurity.c 

Viola! modsecurity module was successfully compiled.
