Installing OEM 10.2.0.5 on RHEL 5.2

Question

Hi all,
I've been trying to install Oracle 10g R2 Enterprise Grid Control on RHEL 5.2 32-bit for week now with no luck.
In OUI, the Configuration assistant "Agent Configuration Assistant" failed.
When I tried to start it manually, I got the following error:
emctl start agent
Oracle Enterprise Manager 10g Release 10.2.0.1.0. 
Copyright (c) 1996, 2005 Oracle Corporation. 
Starting agent ..... failed.
The agentTZRegion value in /u01/app/oracle/product/10.2.0/agent10g/sysman/config/emd.properties
is not in agreement with what agent thinks it should be.Please verify your environment
to make sure that TZ setting has not changed since the last start of the agent.
If you modified the timezone setting in the environment, please stop the agent
and exectute 'emctl resetTZ agent' and also execute the script mgmt_target.set_agent_tzrgn(<agent_name>, <new_tz_rgn>) to get the value propagated to repository.
Consult the log files in: /u01/app/oracle/product/10.2.0/agent10g/sysman/log
I tried the steps to fix the TZ issue but eventually I knew it's a bug fixed in patch 10.2.0.5. But I cannot
apply batch with the installation itself not finished yet.
When I ignored the error and clicked on Next, the installation finished without creating the repository db.
Is there any step-by-step guide on installing Oracle 10g Enterprise Grid Control on RHEL 5.2 32-bit that really works?

Thanks for the hint. It was really useful to me.
I re-did everything, in OUI I specified the software parent location as /u01/app/oracle/product/10.2.0
Yet, OUI created a directory /tmp/u01/app/oracle/product/10.2.0/db10g and installed the db there!
