Note the "%4" instead of "%v4" in there.

Those are real bugs, but harmless.

Either because that's where your cwd was when starting openswan, or because that's
where dumpdir= is pointing to. I am not sure why it returns a failure though. I've
noticed that elsewhere, and looking at the code, I just don't understand why it is
giving an error.
