OpenVZ web panel cron gives ERROR: 'rake/rdoctask'

Hi,

I'm using OpenVZ on CentOS 6.5 64bit and every morning I'm getting message with 
following content:

/etc/cron.daily/owp.cron:

/usr/lib64/ruby/gems/1.8/gems/rake-10.3.1/lib/rake/rdoctask.rb:4: ERROR: 
'rake/rdoctask' is obsolete and no longer supported. Use 'rdoc/task' (available 
in RDoc 2.4.2+) instead. (RuntimeError)

from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in 
`gem_original_require'
from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'
from /opt/ovz-web-panel//script/cron_runner:11

Can anybody help me?

Thanks!
