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
