If your boss can't parse CSV files, presumably (s)he has some other skills - find out what they are and learn them.
You're supposed to be working together right? So go teach your boss how to parse CSV files (nicely).
I this is probably the real error. Lacking greater context, what made you expect that your boss at this new position would be able to mentor you?
Is he supposed to know how to parse a CSV? (Manually? Like, with awk or something?) Or is that why he hired a hacker/programmer like you?
I'm not saying your boss isn't incompetent. Maybe he is. But you shouldn't expect that your superior is always going to be more technically competent than you.
Be patient, there may still be something useful you can learn from the Old War Horse.
Sometimes we learn by teaching. Your boss might welcome and appreciate a tutorial on Parsing CSV files. Assuming the work environment is otherwise congenial, your job can serve as a research lab to master your craft.
