I know it works

You can only conclude that it works from the server itself. Is your perl program also running & connecting from the server?

Your code works for me. That means probably that you have to tweak your pg_hba.conf:

Pg authentication docs (NOTE: change '/current/' to whatever pg version you use; 'current' means Pg version 9.0 - and yes, it has changed).

Oh wait, I see you have 8.4, so here: 8.4 Pg authentication docs

Keep in mind that the first matching line (in pg_hba.conf) will be used.

irc freenode #postgresql is often the quickest way to get postgres database problems solved, or at least, discussed. The DBD:Pg author(s) are often there too.

UPDATE: if you leave the $dsn 'host=' param away, connection will be done via unix sockets (as opposed to tcp/ip).
