[libvirt] help for libvirt0.9.8 compile

[hero]

my redhat6.1 has a libvirt0.8.7, and I got a libvirt0.9.8.tar that I want to update the old one.
when I use
'./configure --prefix=/usr --libdir=/usr/lib64 --localstatedir=/var --sysconfdir=/etc'
it siad 'configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt'
 
please tell me how to do if you know.
thanks.
best wishes!
