Apache issue after installing EBS R12 on Linux x86

EBS R12 installed on a Red Hat Enterprise Linux AS release 4 (2.6.9-5.EL)

After the install, when trying to start up the http server, this happens:

$./adapcctl.sh start
.
You are running adapcctl.sh version 120.6
.
Starting OPMN managed Oracle HTTP Server (OHS) instance ...
.
adapcctl.sh: exiting with status 204 
.
adapcctl.sh: check the logfile
$INST_TOP/apps/CONTEXT_NAME/logs/appl/admin/log/adapcctl.txt for more information.

Workaround:

Remove the parameter -DSSL in the ohs_start() function as follows:
.
$/<?>ora/10.1.3/Apache/Apache/bin/apachectl:

$ diff apachectl.original apachectl.mine

129c129,130
> eval ohs_start -DSSL "$args"
---
> # eval ohs_start -DSSL "$args"
> eval ohs_start "$args"

Restart Apache.

This is however a temporary solution. The main problem is due to not Installing all the Linux RPMS as per the R12 installation document (Note.402310.1). This has to be implemented so as to have a permanent workaround.
