Error building PL/Perl (Postgres) under Cygwin

(note:  i posted this earlier this week and didn't receive any answers,
        i'm hoping that maybe people just missed it.  kevin & jason, my
        apologies for addressing you directly, but you answered analogous
        questions this week about postgres on nt and hoped you may be able
        offer some insight.  THANKS!!!)

I've successfully gotten Postgres and Perl working on a cygwin port,
and am now trying to get PL/Perl to work as well.

(PL/Perl is a plugin to the Postgres Database which allows
one to create functions within the RDBMS written in Perl)

Here are the specs:
Windows NT Workstation, 4.0 (S.P. 6a)
Cygwin DLL v. 1.1.4(0.2632)
Postgres 7.02
Perl 5.6.0
CygIPC 1.07-1

I successfully followed the instructions for installing Postgres at this url:
http://people.freebsd.org/~kevlo/postgres/portNT.html

And I successfully used the binary perl distribution from here:
http://cygutils.netpedia.net/V1.1/perl-5.6.0/index.html

However, when I goto $POSTGRES_SRC/src/pl/plperl and run
$ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/perl5/5.6.0/cygwin/CORE:/usr/local/bin \
  perl Makefile.PL POLLUTE=1
$ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/perl5/5.6.0/cygwin/CORE:/usr/local/bin \
  make
I get the messages appended at the end of the email.  I'm having trouble deciphering
these messages and determining whether this is a "Cygwin" issue or a "PLPerl" issue, and
what exactly to do about fixing it.

My questions:
*  Is this a problem with cygwin's ld2 or dllwrap?  or is it a problem where the perl distro
   i am using didn't have an "export definition file" with it?  or ???
*  What can I do to fix it :)

Thanks!!!
