Mod_perl Installation Issue

[Cure]

I'm currently using Freebsd 5.3 and Apache2, I'm trying to install 
mod_perl2 from ports but I get the following error -->

make install
===>   mod_perl2-2.0.0r3,1 depends on file: /usr/local/sbin/apxs - found
===>   mod_perl2-2.0.0r3,1 depends on file: /usr/local/bin/perl5.8.6 - found
===>  Configuring for mod_perl2-2.0.0r3,1
