If I was reliant on a paycheque being paid in each month, I'd ensure that there was always sufficient funds in the account to cover and SO's/DD's for eventualities like the one you describe. Obviously it's not your fault you were paid late but what would have happened if he'd been seriously injured or killed, just before he was supposed to authorise wage payments?
As others have said, re-schedule your outgoing payments from your account or it's just possible it could happen again.
Your boss may have authorised late payment and you could ask him for any out of pocket epenses which are a direct result of paying you late and he may agree to this but, he is not responsible for your personal finances and I would suspect that he's not legally ( if morally) responsible for any losses you might have incurred, unless it was part of your contract of employement.
