For DBI/DBD to work, you'll need libpq, which contains the actual code to
interface with PostgreSQL. It should be possible to only install (ie.
copy) libpq.{a|so} and the necessary include-files to those machines, and
then install the DBD driver. You could probably put all the necessary
files in a .tar.gz file (write a little script to do this), so it's easy
to distribute those files (and to keep the machines up-to-date when you
upgrade PostgreSQL).
Maybe it's an idea to include such a script in the main distribution. It
should place all necessary libraries and include-files, and maybe the
user tools like psql.
If you're running a Debian/Linux system, you're in luck. There already
exist the necessary packages (libpgsql, libpgperl (postgresql specific),
libdbi-perl, couldn't find libdbi-pgsql however, someone should create this).
