svn-push fails with SubversionException: Can't create directory, perm. denied

Hi, I was following tutorial at http://doc.bazaar-vcs.org/latest/en/user-guide/index.html#bzr-svn

When I wanted to push changes back to the SVN repo, exception occurred. Since I work under OSX /home/svn/... is not writable. Is there a way I could specify directory where svn would create its db or whatever it needs to push changes?

Thanks! Below is the exception backtrace.
