CentOS 6.5: Howto install GTK version 2.8.0?

Question

I am running CentOS 6.5, kernel2.6.32-431.5.1.el6.x86_64 #1 SMP. I am trying to install Rattle - data mining tool for R programming language. Rattle is installed from R shell. Notwithstanding I have latest GTK installed, when trying to install Rattle I get configure: error: GTK version 2.8.0 required (see below). How to solve this?

R version 3.0.2 (2013-09-25) -- "Frisbee Sailing"

The package 'RGtk2' is required to display the Rattle GUI. It does not
appear to be installed. This package (and its dependencies) can be
installed using the following R command:

install.packages('RGtk2')

This one-time install will allow access to the full functionality of
Rattle.

Would you like Rattle to install the package now? (yes/NO) yes

To solve the problem gtk2 development library must be installed. Under CentOS this can be done with:

yum groupinstall "Development Tools"
yum install gtk+-devel gtk2-devel
