installing mlocate package on freebsd

Hello everyone ,

forgive me if this the wrong place to post my question .
i got a pfsense box ( FreeBSD 8.1-RELEASE-p4 )
i need to know how to install the "mlocate" package to be able to use the command "locate" on the Box

Thank you

setenv  PACKAGESITE="ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8-stable/Latest/"

look for your package "pkg_search" but before

pkg_add -rv pkg_search

pkg_search locate

locate the package and

pkg_add -rv $package

I hope it will serve.
