plperl failure on OS X 10.5(.1)

I mentioned in #postgres a bit ago to no avail that I couldn't get my
plperl stored procedures to work after upgrading to OS X 10.5, with only a
obtuse "ERROR: null prosrc". I was using 8.2.4 and didn't want to make a
big deal about a non-current release, but today I had a chance to build
8.3 and 8.2.5 and am seeing the same behavior.

I don't see 10.5 in the build farm list, so I thought I would ask if this
is a known issue.

A synopsis:
configure, make and install a fresh postgres and database (configured
--with-perl --with-python --with-openssl). This is on my G4 powerbook.
createlang pgperl
attempt to create a perl function, e.g. the perl_max function from the
docs (http://www.postgresql.org/docs/8.2/static/plperl-funcs.html):
$ cat perlmax.pl.sql
CREATE FUNCTION perl_max (integer, integer) RETURNS integer AS $$
if ($_[0] > $_[1]) { return $_[0]; }
return $_[1];
$$ LANGUAGE plperl;
$ ~/local/pg-8.3b3/bin/psql -f perlmax.pl.sql test
psql:perlmax.pl.sql:4: ERROR: null prosrc

there were a few warnings building plperl:

nothing fatal... and a more worrisome warning when linking libperl:

ld: warning in plperl.o, file is not of required architecture
ld: warning in spi_internal.o, file is not of required architecture

I don't have terribly much time to figure out the guts of plperl, but
would be glad to provide any more information or a login to an OS 10.5
host if that can help...

Thanks for everything,
