Many of these environments rely on checking against a known-good checksum.
If a tarball is replaced at the source, that checksum changes.  Once a
release is cut, that particular release should never change.  If a change
is necessary, some sort of point release (3.2.1) is preferable, so anyone
wanting 3.2 still gets the old binary with the old checksum.
