Assume the author of ImageMagick updates his tarball, but doesn't change
the name, so that there are two ImageMagick-5.2.9.tar.gz with distinct 
sha1 checksums.

On OpenBSD mirrors, the old one stays available, under
sha1/<checksum>/ImageMagick-5.2.9.tar.gz

If I understand you correctly, your build/update cycle will overwrite
the old one. And users will have to update their ports tree to be able
to use the new tarball without a checksum error, since the old one is no
longer available.
