r413 is a subversion source code version
so yes, you would have to build it yourself. Although as I said in my previous post, it doesn't actually fix the problem from the topic title - that was a mistake on my part.
If you do want to build it, I believe there are some instructions in the source code if you have never done it before.
In a nutshell: you need to install subversion, a JDK (if you don't already have one) and ant, then check out the code and follow the instructions to run the ant script. If you didn't understand any part of that sentence, you have a bit of research to do
