Can't find anything via the Google that states he can't have license. May be best to purchase online rather than in person though. Example the DMV could refuse service, call the law or if law enforcement is in the building have them detain you for the warrants. So probably best to purchase online and stay out of any official buildings.
Best bet is to handle warrants and be on the right side of things but if not possible I cant locate anything stating he can't hunt....unless he's a felon then it's a whole other problem with firearm possession.
Disclaimer: I'm not a lawyer and this isn't legal advice, just some simple advice after some Google digging out of curiosity on the topic.
