I get no error message with Subversion 1.4.2, but "svn diff -x -b"
does not ignore whitespace, if that's what you wanted. If so, realize
that you need to specify the name of the external diff command,
otherwise Subversion uses its internal diff implementation, which
presumably does not support -b. Do this:

svn diff --diff-cmd diff -x -bu

That does invoke the external diff command with whatever parameters
you specify.

Side note: On my system (Mac OS X) diff -b seems still not to ignore
whitespace differences, which is odd since the manpage says it
should. But... that's my problem. Hopefully it works for you.
