Since i didn't want to have to go down that route i decided to build mod_security based on the version of Apache that ships with Centos 5.x / RHEL 5.x Now I cannot take full credit for creating the srpm which i copied from www.modsecurity.org
But i have built the associated rpm based on the version of Apache shipped with Centos 5.x / RHEL 5.x using the well written spec file created by the aforementioned site.
The link to the package is listed below, if more references are required in how to customize mod_security please consider going to the www.modsecurity.org website.
*** UPDATE ***
Rebuilt the 2.5.12 version of the fedora rpm for centos using the centos libs enjoy.
