Package from the packages-5.1-release directory won't install on a 5.1 system

I have a stock 5.1 release system, but when I try to install the package amsn-0.71_1.tbz, which I downloaded from ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-5.1-release/All/amsn-0.71_1.tbz pkg_add says it needs version tcl-8.4.3,1 of tcl but my 5.1 system has tcl version 8.3.5_2

pkg_fetch argument syntax question

The man page for pkg_fetch says this: The following command line arguments are supported: pkgname Specify a full pkgname, a pkgname without version followed by an @, or a full URI. But it doesn't say what appending a '@' to the package name means.
