Time Zone Names Problem

I'm running PostgreSQL 8.0.1 from the NetBSD pkgsrc package. I'm getting some
odd behavior with time zone names:

SET timezone TO 'JST';
psql:z.sql:1: ERROR: unrecognized time zone name: "JST"
SET timezone TO 'EST';
psql:z.sql:2: ERROR: unrecognized time zone name: "EST"
SET timezone TO 'Asia/Tokyo';
psql:z.sql:3: ERROR: unrecognized time zone name: "Asia/Tokyo"
SET timezone TO 'US/Eastern';
psql:z.sql:4: ERROR: unrecognized time zone name: "US/Eastern"
SET timezone TO 'Asia/Tokyo-9';
SET
SELECT '2004-08-22 18:42:12' AT TIME ZONE 'Asia/Tokyo';
psql:z.sql:7: ERROR: time zone "asia/tokyo" not recognized
SELECT '2004-08-22 18:42:12' AT TIME ZONE 'Asia/Tokyo-9';
psql:z.sql:8: ERROR: time zone "asia/tokyo-9" not recognized
SELECT '2004-08-22 18:42:12' AT TIME ZONE 'JST';
timezone
---------------------
2004-08-22 18:42:12
(1 row)

Anybody have any idea what's going on here? The only patch pkgsrc makes
is related to shared library version numbers for a couple of operating
systems, so I don't think that this is package-specific. It may be
NetBSD-specific, however.
