[ADMIN] having problem with postgresql-6.4.2

[hoelc]

Hello,
I'm trying to install postgresql-6.4.2 on my RedHat Linux 5.0.
and got this error massage when creating database installation from
postgres superuser(postgres), with command ' $ initdb '

            :
     { this is the end part of the massage, where I notice some error }
            :
initdb:Creating template database in /var/lib/pgsql/data/template1
