Subversion's checksumming makes sure that you get exactly the same files
that are on the Subversion server at this particular moment in time.

The Ports Collection's distfile checksums make sure that you get exactly
the same files *as the port maintainer examined at some previous moment
in time*.

The difference is crucial.

  svnadmin create /home/svn/foo

  svn import http://.../foo/trunk/mycoolproject
 =20
  <create a port of mycoolproject>

  rm -rf /home/svn/foo

  svnadmin create /home/svn/foo

  svn import http://.../foo/trunk/mycoolproject

=2E..and suddenly the port fetches something completely different.

G'luck,
Peter
