Thanks, I didn't realize that the install order doesn't matter.  But in 
the longer term, he'll probably want to do this himself, so he'll still 
need to generate the list of dependencies and download them.  Or maybe 
just burning a copy of the installed library is what he should do --- 
I'd just be worried about versioning issues if he tries to update the 
install without starting from scratch.
