Hello,
When I want to install libvirt-0.10.0 from source, I get this error at the configure stage

checking for libdevmapper.h... no
configure: error: You must install device-mapper-devel/libdevmapper >= 1.0.0 to compile libvirt

However the package is installed on my system

# yum list device-mapper-libs.x86_64
Installed Packages
device-mapper-libs.x86_64                                1.02.74-10.el6                                @base/$releasever
 

What is the problem then?

Regards,
Mahmood
