I'm very suspicious as to this actually being the code causing that message since there's no use of eq in it anywhere; I'd expect to see Use of uninitialized value in pattern match (m//) at ... (or Use of uninitialized value in regexp compilation at ..., depending on the side of the =~ the undef is showing up) instead.

Update: Added other possible expected error message.
