Install Postgresql on Linux Friendlyarm

Gerry
Hi,

I'm newbie here so I'm sorry if this is posted in a wrong place.

I tried to install Postgresql 9.2.9 on Linux Friendlyarm. The Postgresql
was cross compiled successfully on my desktop Ubuntu. Then it was moved to
Linux Friendlyarm environment. When I tried to start the Postgresql server,
it gives me the following error:

LOG: could not create IPv4 socket: Permission denied
WARNING: could not create listen socket for "127.0.0.1"
FATAL: could not create any TCP/IP sockets


The kernel info. of my Linux friendlyarm is as follows:
Linux FriendlyARM 2.6.35.7-FriendlyARM #1 PREEMPT Thu Mar 1 17:38:57 HKT
2012 arm7l GNU/Linux.

Anyone could provide some help about this? 
Thanks in advance!
