Sorry, I misread.  Yes, you do need those patch files in your local mirror.
In fact, if you look at ${BUILD}/downloads, every _file_ (not symlink) that's
at the top level needs to be copied.  I manage this by running a script
like this:
   (cd downloads;find . -type f -maxdepth 1 | tar -cT - | tar -x -C ${DL_DIR})
