Just to clarify I think you need dbi-link. I believe that db-link only allows to you connect to
other postgresql databases.

I found the following from :
http://www.postgresql.org/docs/8.1/interactive/plperl.html

Note: Users of source packages must specially enable the build of PL/Perl during the installation
process. (Refer to Section 14.1 for more information.) Users of binary packages might find PL/Perl
in a separate subpackage.

and "section 14.1"
http://www.postgresql.org/docs/8.1/interactive/installation.html#INSTALL-SHORT

I hope this helps. I am sure someone else on the list with more experience will be able to get
more specific information if you need it.
