Unable to make DBD-Pg-2.13.1

I'm new to PostgreSQL. Just installed the latest version, 8.3.7, on my
FreeBSD system (client + server). All went well...

Until I tried to install DBD-Pg-2.13.1 (for Perl) thereafter. And I'm
getting the weirdest errors that just won't go away (see below). Does
anyone know what the cause might be? Or better still, how to fix it? :)

Thanks,

- Mark
