I have been trying to install open-xchange community version on my vps running CentOS 6.2. I have found a thread detailing the installation on centos 5 and followed those instructions. However, I still cannot seem to complete the installation of open-xchange. My linux (and more so, centos) knowledge is limited. Perhaps I am missing something quite evident and obvious. If i install the complete server (as one stand-alone server) by either running the command:
$ yum install mysql-server open-xchange-meta-centos open-xchange-meta-singleserver \
   open-xchange-authentication-database open-xchange-spamhandler-default
or by using the "install a rpm" feature in CPanel WHM, I get the following output (for both cases):

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base: mirror.ufs.ac.za
 * extras: mirror.ufs.ac.za
 * updates: mirror.ufs.ac.za

 You could try using --skip-broken to work around the problem

Install complete.
To my knowledge perl:cgi is installed. when I try to install perl:java (via cpanel perl package install) I recieve the following errors:

Could you please guide me on how I could possibly resolve this problem and have a working version of open-xchange on my vps.

Much apprecaited.
