pkg_add on machine without Internet connection

[Ray Phillips <r.phillips%uq.edu.au@localhost>]

I'd like to install some binary packages on a NetBSD/i386 machine 
which has no connection to the Internet.  One of the packages I want 
is kde; I know I can get this file:

ftp://ftp.netbsd.org/pub/pkgsrc/packages/NetBSD/i386/5.0.2_2010Q2/All/kdebase4-4.4.4nb1.tgz

transport it to the machine in question via a USB memory key, then run:

# pkg_add /path/to/binaries/kdebase4-4.4.4nb1.tgz

but how do I find out which packages kde depends on so I can fetch 
their .tgz files and put them all in one directory prior to running 
the command above?
