initdb fails on Centos 5.4 x64

Hi,

i've tried to install 8.4.3 for about two days, but i don't get it.

8.1.x has been installed before and was runnig but never used. I've removed it with yum and wiped /var/lib/pgsl.

-=>> service postgresql initdb
Initializing database: [FAILED]

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.

The database cluster will be initialized with locale en_US.UTF-8.
The default database encoding has accordingly been set to UTF8.
The default text search configuration will be set to "english".

The server is running with 8 gigs ram, so i think there should be enough mem?

Thanks,
