1) Did you do a 'make distclean' from your application top directory first?  

Now two unsolicited suggestions:

1) Is your application invoking this subroutine for anything other than startup/initialization?  If you plan to invoke this subroutine during regular IOC operation I think that you are using record processing improperly.  "Slow" I/O operations should not be performed in the context of record processing.  You should use the ASYN support module instead -- this will allow your application to perform the I/O in a separate thread and not interfere with processing of other records.
2) The aSub record is  now distributed as part of base.   This record is more capable than genSub and requires no extra support modules to be added to your application.
