Sounds like everyone's recommending just removing it. Just in case you're the one site using extproc callouts, you might want to check dba_libraries to see if any have been registered. I'm not positive that an empty dba_libraries means that you're in the clear, but I'm pretty sure you'll see some obviously custom entries in there if someone has created a library for callouts. I don't believe that Peoplesoft uses any extproc callouts (it sort of violates their "database-independent implementation" style). Of course, you could just comment it out and wait for the phone to ring. That's probably what I'd do :).
