oraperl error: Undefined sub "main'ora_login"

When I try to run an oraperl program from a setgid program, all I ever get is:
Undefined subroutine "main'ora_login" called at /use/library/prod/bin/bradr line 55.

If you know why, please tell me!
(I DO have #!/usr/local/bin/oraperl in my oraperl program) Received on Tue May 24 1994 - 22:12:58 CEST
