Well, first of all, install an RPM or other type of package if you can.

If you can't, run this command:

    perl Makefile.PL

It will show you if anything is missing, e.g.:

    Warning: prerequisite DBD::Pg 2.0 not found.

Use your packaging system to install dependencies if you can (usually called perl-Something, in this case perl-DBD-Pg), or else use the CPAN client:

    cpan DBD::Pg

Sounds like your distribution's PostgreSQL 9.0 package is horked.

Yes, PostgreSQL 9.1 has been released and stable for several months.

We probably ought to mention that the PostgreSQL build requires PL/Perl.

Appreciated!
