Did you read the 'svn help diff' that Sussman suggested?

...
        3. diff OLD-URL[@OLDREV] NEW-URL[@NEWREV]
...

It is always possible to do diffs between any two URL's in the repository. What
Sussman was saying (if I can paraphrase) is that svn does not handle two local
paths (since you have a perfectly good GNU diff that can do that).

So you can do this:

        svn diff $REPOS/tags/version1 $REPOS/tags/version2

as long as $REPOS is svn://, file://, or http:// but not a path in the local
filesystem.
