Seems this old, legacy software has been removed from the vendor site.
Only macOS and Windows versions are still available from stuffit.com.
A few mirrors exist, including on the Wayback machine, but that one does
not seem to offen a suitable direct download link.
Therefore, small mirror sites have been selected that currently offer
the Linux version - a quick search did not result in any better mirrors.
The PORT_REVISION is not incremented since there is no other change than
the download address - packages need not be rebuilt.
