Problem Using Perl with Postgres

I have installed postgresql 7.1.2 on my Solairs 2.7 box with the
with-perl option.
I did not have any compile errors.

When trying to run a simple perl program I get the following error:

$ tst.pl
Can't locate loadable object for module Pg in @INC (@INC contains:
/ufs/gnu/postgresql-7.1.2/src/interfaces/perl5
/usr/local/lib/perl5/5.00503/sun4-solaris /usr/local/lib/perl5/5.00503
/usr/local/lib/perl5/site_perl/5.005/sun4-solaris
/usr/local/lib/perl5/site_perl/5.005 .) at tst.pl line 4
BEGIN failed--compilation aborted at tst.pl line 4.

The third line in the program is
use lib '/ufs/gnu/postgresql-7.1.2/src/interfaces/perl5';
use Pg;

The following is how the perl package was installed in my system.
Any ideas?
