Akk,
What's going on is that while libxslt1-dev version 1.1.22-1ubuntu1.2 to match your installed binary package is available in hardy-security, your computer's ignoring it. It's ignoring it because your priority on main is set to 990, making it automatically prefer the not-security-patched versions ahead of the patched versions (see man 5 apt_preferences).
Ubuntu defaults to 500 for everything so that version number rules. Do you have an apt preferences file somewhere that's interfering?
