Problem with initialization

Hello everybody,

We are using postgres at Fermi lab since long. But we have not been able to successfully install it on one of our red hat machine recently after a lots of efforts. The OS is Red Hat linux release 5.2(
Appollo), kernal: 2.0.36 (on i686). The installation procedure does not complain anything, but the initdb fails with following message:

initdb output:

initdb: 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=60).
This user will own all the files and must also own the server process.

****

The postgres version is 6.4.2; we are using the same version on a different machine which has Red Hat-5.0(Hurricane) with kernal 2.0.35 on i586; and it functions smoothly.

Is there any problem with OS? (we have checked almost everything upto IPC, shared memory settings). Please reply us asap as we are on tight schedule.

Thanks a lot,
