plperl on AIX

I posted this in other lists with no response... Can anyone help?

I'm having trouble getting plperl to work on AIX 5.3.2.
Postgresql Version: 8.1.1
Perl Version: 5.8.7

I've rebuilt perl as a shared library version and built that into postgre
using --with-perl. The postgre build/install works fine, without errors.

The plperl regression tests all fail, though. Here are the test results
of the first regression test:

--
-- checkpoint so that if we have a crash in the tests, replay of the
-- just-completed CREATE DATABASE won't discard the core dump file
--
checkpoint;
--
-- Test result value processing
--
CREATE OR REPLACE FUNCTION perl_int(int) RETURNS INTEGER AS $$
return undef;
$$ LANGUAGE plperl;
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
connection to server was lost

I've tried this same thing manually with the same result.

Does anyone have any suggestions on how to get this to work?

Thanks
