DBD::Pg install error (freebsd)

I'm trying to install (from source) DBD::Pg v1.01 after having
installed (from source) DBI v1.19 on FreeBSD 4.3 (Release) and I
encounter this error in the 'make test' step:

dell_box# make test
PERL_DL_NONLAZY=1 /usr/bin/perl -Iblib/arch -Iblib/lib
-I/usr/libdata/perl/5.00503/mach -I/usr/libdata/perl/5.00503 test.pl
OS: freebsd
install_driver(Pg) failed: Can't load 'blib/arch/auto/DBD/Pg/Pg.so'
for module DBD::Pg: Shared object "libpq.so.2" not found at
/usr/libdata/perl/5.00503/DynaLoader.pm line 169.

at (eval 1) line 3
Perhaps a required shared library or dll isn't installed where
expected
at test.pl line 53
*** Error code 255

Stop in /usr/home/jake6006/DBD-Pg-1.01.

I have POSTGRES_LIB and POSTGRES_INCLUDE properly defined (else 'make'
wouldn't have worked). In fact, for additional reference I've provided
the output from 'make'. I'm running these things as root instead of
postgres... does it matter?

I'd appreciate any help offerred. Thanks.
