Install ziproxy Package

[mystycs]

Im trying to install ziproxy here on pfsense http://ziproxy.sourceforge.net/download.html

It says its part of FreeBSD but when i put the command in terminal

pkg_add -r ziproxy

I get this error below.

]/root(5): pkg_add -r ziproxy
Error: Unable to get ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.1-release/Latest/ziproxy.tbz: File unavailable (e.g., file not found, no access)
pkg_add: unable to fetch 'ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-8.1-release/Latest/ziproxy.tbz' by URL

Is something wrong with my FreeBSD or do i have to enable something?
