fetch package dependencies

[Dorian Büttner]

Hi all,

is there an easy way to fetch a package along with it's recursive 
dependencies? Scenario is:
eee904ha does not have network access at all right now. In order to 
proceed installing useful things, let's say firefox, I'd like to suck 
packages onto a usb stick and installl from there.
I thought I could go to the soekris box, which unfortunately isn't that 
-current, and do something like pkg_add -n mozilla -firefox,  but the 
output is totally garbled with libc mismatches and things like that.

Any idea?

Thanks,
Dorian
