install evms on centos using yum

i'm refering this page

http://75.126.99.220/showthread.php?t=1062710

1) Get and *install rpmforge. http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

2) "sudo yum update". It'll take a while to add the new repository. It'll probably download some packages, too (30 megs in my case, but only 8 packages from rpmforge).

3) "yum search evms".

4) "sudo yum install evms.i386".

now installing :)

*install rpmforge: rpm -Uvh rpmforge*
