Dan,

If you arent aware there is a very good freeware developer tool called toad(www.toadsoft.com). This tool will allow you to 1). create different database logins within same toad session. 2). It has a procedure editor that will allow you to pull procedures, functions, packages.... by schema owner.

So you could create 2 database sessions(1st sess would be where your package is currently located, 2nd sess would be where you want to copy package to).

Load up procedure editor from session one, pull in you package, click blue button(menu bar). This action will select all code. Pull up procedure editor from session two. The click ctrl-v. Once code is in procedure editor(session two). then click compile.

Hope this helps.
