I hate to suggest it, but all i can find is DBD::ODBC. Maybe you could Write a new one, which would help the next person to ask ... but that, as they say, is a non-trivial excersize.
Update : I found a reference to DBD::OpenBase hereand the resume of the person working on it here ... appears a DBD is in the works.
i had a memory leak once, and it ruined my favorite shirt.
