Fatal Error Cpanel Installation Perl Must Be Installed Centos

While I install cpanel in my VPs. I got the following error message.

Error Message:which: no rdate in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin :/root/bin)

./bootstrap: line 14: [: argument expected

Current system time is set to: Fri Jul 16 13:10:09 EDT 2010

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Unable to verify system time. Utility to set time from a remote host, rdate, is not installed in PATH.
If your system time is skewed greater than a few hours, then source compilations will subtly fail.
This may result in an overall installation failure.

To Resolve These Problem
First we need to install Perl
#yum install perl
Then try it will work perfectly.
