[CentOS] missing package in centos 6 - gtk+

Hi all,

Was installing centos 6 and found this: ./CentOS-5.6-x86_64/CentOS/gtk+-1.2.10-56.el5.i386.rpm ./CentOS-5.6-x86_64/CentOS/gtk+-devel-1.2.10-56.el5.i386.rpm ./CentOS-5.6-x86_64/CentOS/gtk+-devel-1.2.10-56.el5.x86_64.rpm ./CentOS-5.6-x86_64/CentOS/gtk+-1.2.10-56.el5.x86_64.rpm ./CentOS-6.0-x86_64/Packages/gtk+extra-2.1.1-13.el6.i686.rpm ./CentOS-6.0-x86_64/Packages/gtk+extra-devel-2.1.1-13.el6.x86_64.rpm ./CentOS-6.0-x86_64/Packages/gtk+extra-2.1.1-13.el6.x86_64.rpm ./CentOS-6.0-x86_64/Packages/gtk+extra-devel-2.1.1-13.el6.i686.rpm

Where is gtk+? Its in 5.6 but not in 6.0?
