ClientExec And WHM

I just purchased ClientExec from my webhosting company.

I have WHM 11.20.0 cPanel 11.22.0-E23176
CENTOS Enterprise 5 i686 on virtuozzo - WHM X v3.1.0
and for CE i have Version 3.0.2

Now. When I try to have a customer register, everything goes fine.... EXCEPT!

1: The account does not get set up automatically, under admin > plugins > services i see

Quote:

NOTICE: Crontab is not available in your system or you don't have permission to use it. Therefore, you must enable the plugins you wish to use, and manually enter through your hosting control panel its correspondent cron job.

I scroll down to the plugin i want to use (Order Processor)
and it says

Quote:

Cron Job: Error: couldn't find location of PHP binary

Now. I think this may be related in some way, but am not sure...
When i try to activate an account immediatly, i get this

Quote:

Cpanel Account Creation Failure: The package was not found on the server. Package CE4 testdomainnet.org has been activated. Package(s) activated successfully

I have given CE (under admin > servers > servers)
my root login to WHM, and its password, and have selected Cpanel...
