Initdb cannot work with postgres 6.3.2 under RH5.0

Hi.

Installing postgres 6.3.2 on RedHat 5.0 by following the steps when
running initdb, i got

nitdb: using /usr/local/pgsql/lib/local1_template1.bki.source as input
to create the template database.
initdb: using /usr/local/pgsql/lib/global1.bki.source as input to create
the global classes.
initdb: using /usr/local/pgsql/lib/pg_hba.conf.sample as the host-based
authentication control file.

We are initializing the database system with username postgres
(uid=505).
This user will own all the files and must also own the server process.

initdb: creating template database in
/usr/local/pgsql/data/base/template1
Running: postgres -boot -C -F -D/usr/local/pgsql/data -Q template1
WARN:heap_modifytuple: repl is \ -9
initdb: could not create template database
initdb: cleaning up by wiping out /usr/local/pgsql/data/base/template1


Pls help me to settle "WARN:heap_modifytuple: repl is \ -9" ?
