could not create IPv6 socket when starting Postgres server

A new Postgres server 8.2.4 was installed on an IRIX platform, but I was unable to bring up the Postgres server clean.

When using postmaster to start the server, the server is up but with the IPv6 error.

when using "pg_ctl start" to start the server, the Postgres server won't come up at all.

How do I get right of this IPV6 error and start the server clean. Besides, I want to be able to start the server with pg_ctl. I have been staring psotgres with pg_ctl for a long time on other machines.

If there anything that our system administrator can do to help me get rid of this IPv6 error? We have other Irix machines running Postgres, I starting Postgres fine on them.

Thanks,
Jessica
