Non Network cvsup?

[Daniel Bass]

So my IT department won't open port 5999 so I can't access the servers 
with cvsup.
Is there some manual method to synchronize my installation?  Can I just 
ftp a recent
copy of  ports.tar.gz and replace my installed /usr/ports directory? In 
particular, I just
installed 5.3-Release from cdrom, and it installs Xorg 6.7 rather than 
6.8.2; and I
don't know what else is already out of date.

Thanks,
