Obtaining portsmanager meta package for alternate OS

[Garrett Cooper]

Hello,
    I was wondering if anyone could point me to the release notes or 
code so I could look up the dependencies for the portsmanager package 
and possibly compile it on Mac OS X Tiger.
    My FreeBSD machine is currently at home (sadly without an internet 
connection to the outside world :(), and I would like to keep it up to 
date by periodically fetching the ports 'source files'/packages and port 
snapshots. So I thought I could accomplish this via building the 
portsmanager package and running it off of my laptop at school since 
it's the only way I can accomplish my task at hand.
    However, with that in mind, I was wondering if there was a better 
way to fetch ports/packages without having to manhandle too many 
programs/scripts, or if anyone has discovered a better solution to this 
type of 'issue'.
    Thanks and your responses are greatly appreciated as solving this 
'problem' will help save me a great deal of time :)!
