OK...  that simply means you need to download that file again.  Probably if
you look at the size, and then check the size on my ftp machine, they will
not agree...

About the only viable choice is to download it again.  Building the things is
very time consuming and requires a lot of RAM (512MB) plus a lot of free disk
space.  And it requires that you have _all_ the promotion cases as well.
