building a package without installing it

[daniel quinn]

is this even possible?  a number of google results have informed me that it 
isn't, but i'm hoping there's a hack or a work around.  essentially, i want 
to build the packages on one box, copy them to many boxes and run package_add 
there.

suggestions/comments?
