Do you think it will be enough to simply remove the reference? libxenlight still depends on a blktap in the CentOS package, but it is a different one that don't have a .pc file. It is easier to remove the reference that to try to write a new .pc file :-). There is xen-4.12.2-2 package that should be available in the testing repo in a couple of hours. Thanks, -- Anthony PERARD
