Xymon installation issue

Hi all,

I'm currently setting a system (CentOS 6.2) with all the requirements as mentionned in CE 5.0 Installation Guide.

I'm at the stage of installing xymon. As described at http://knowledge.kaltura.com/kaltura-ce-v50-installing-xymon-monitoring-...

I downloaded both the server and the client on kaltura site and tried to install them.

1. Installation of rpms :
Installation of the server using rpm seems to be successfull but the one for the client is failing.
Here is the message I'm getting :
[root@localhost kaltura-setup]# rpm -ivh xymon-client-4.3.7-1.x86_64.rpm
error: Failed dependencies:
xymon conflicts with xymon-client-4.3.7-1.x86_64
xymon-client conflicts with xymon-4.3.7-1.x86_64

What does it means ? We cannot get the server and the client running on the same server ?

2. Server issues
Also, when I try to start xymon server, I'm getting some errors : Here is the content of xymonlaunch.log after a "service xymon start" command :

Before changing any rights on the directories and files, I wanted to know what's wrong...

Any ideas about what to do to solve these ?
