Hi, pkg-config files should be in /usr/lib, not in the /lib: andrew@subaru ~ $ qfile /lib/pkgconfig/libipset.pc net-firewall/ipset (/lib64/pkgconfig/libipset.pc) andrew@subaru ~ $ eix -e ipset [I] net-firewall/ipset Available versions: 6.15 (~)6.16 (~)6.16.1 6.17 (~)6.19 6.20.1 (~)6.21.1{tbz2} (~)6.24{tbz2} {modules KERNEL="linux"} Installed versions: 6.24{tbz2}(08:34:37 PM 08/07/2015)(-modules KERNEL="linux") Homepage: http://ipset.netfilter.org/ Description: IPset tool for iptables, successor to ippool
6.29 in the tree, please retest
6.29 still installs the pkg-config file in the wrong directory: taz ~ # qlist ipset-6.29 | grep pkg /lib64/pkgconfig/libipset.pc
