Failed to initialize lc_messages to ''

Hi,

when I try to execute initdb I get the following errors:

---<<< cut >>>---

The files belonging to this database system will be owned by user
"postgres".
This user must also own the server process.

The database cluster will be initialized with locales:
COLLATE: POSIX CTYPE: en_US MESSAGES: en_US
MONETARY: en_US NUMERIC: en_US TIME: en_US

Success. You can now start the database server using:

./bin/postmaster -D /opt/pgsql/data
or
./bin/pg_ctl -D /opt/pgsql/data -l logfile start

---<<< cut >>>---

Can someone help ?

Thanx
