HP-UX Internet Express PostgreSQL (install error)

[Yung_1]

I have installed HP-UX Internet Express PostgreSQL on HP9000 hpux B.11.11

$ echo $PGDATA
/var/opt/iexpress/postgresql
$ pg_ctl start
sh: 9417 Abort(coredump)
fgets failure: No such file or directory
The program "postgres" is needed by pg_ctl but was not found in the
same directory as "/opt/iexpress/postgresql/bin/pg_ctl".
Check your installation.

when I launch postmaster to check i have this result:
$ postmaster
/usr/lib/dld.sl: Unresolved symbol: pthread_mutex_lock (code) from postmaster
Abort

Can you help me ??

>The program "postgres" is needed by pg_ctl

Is postgres there?

>dld.sl: Unresolved symbol: pthread_mutex_lock

What does "chatr postmaster" show? Does it have libpthread?
What version of libc.2 do you have?
