If you feed it the DMG, it will just copy the contents to the root of your HD. Not what you want. Instead, just copy the .mpkg and the other files to a folder, feed LANrev the .mpkg and check the box for "transfer all files in folder containing selected object" and as long as those other files are in the same relative location, it should find them.
Just what i was looking for
Many thanks for your help much appreciated
