Issue with mod_security3

[SoftwareInforJam]

Hi All
I am have a queer problem with the port mod_security3. I actually want to set it up to work with NGINX. The port /usr/ports/www/mod_security3 exists but when I do a 
# pkg install mod_security3 
I get 
“pkg: No packages available to install matching 'mod_security3' have been found in the repositories”

When I do a pkg search “mod_security*” only ap24-mod_security-2.9.2_3      Intrusion detection and prevention engine. So only version 2.9 shows up. Not sure why this is happening. Can anyone shed some light on this please?
