By "repack" I think he means unpacking the .PKG file and then fixing the problem (by moving the "music" to where it belongs) and then repacking it. After all that you can install the fixed .pkg file, so you've essentially fixed the problem by installing a PKG. But It's much easier just to move the folder on multiMAN's file manager imo.
