I'm guessing the issue is that the contents of the files changed with the move to the new repo (i.e. not the actual code, but the other metadata in the files).
Deleting the files locally should fix it. From the PKGBUILD side, one could include the version number in the file names, although the checksum issue is probably a one-time problem.
