I've also dealt with this in the past. I would make sure that the boss knows that the in house programmer is slowing you down and continue encouraging him to improve and adopt some better practices. You don't want to call him out but you also don't want to look like you aren't getting any work done. If you are getting paid by the hour and can deal with the headache, you are getting the better end of the deal anyway. If the boss knows that, they might be more likely to do something about the situation. Good luck. It is a tough situation.
