exporting a new function in prim_file.erl

I'm trying to add a new function to prim_file.erl that will be called by
file_io_server.erl. Therefore I export it in the first export macro.
This new function happens to have exactly the same interface (arity and arg
type, return values) as prim_file:sync/1, so I copied the sync function
clause, renamed it, and added the corresponding export.
After building and installing OTP, I get an error when calling
=ERROR REPORT==== 21-Apr-2010::16:30:53 ===
Error in process <0.35.0> with exit value:
file:my_func/1 just calls file_io_server:my_func/1 wich in turn calls
It seems that prim_file is not exporting my_func. Yet I have an explicit
"-define([... sync/1 my_func/1 ...])."
The Erlang shell is not recognizing prim_file:my_func/1 (through tab auto
My code path also seems to be correct.
What am I missing here?
