Hi, I want to stay with glibc-2.25-r10 until glibc-2.26 mess settles down. I assume I do not need net-libs/rpcsvc-proto at all if my glibc in <2.26. # emerge -N1 app-emulation/libvirt -v --tree [ebuild U ] app-emulation/libvirt-4.0.0:0/4.0.0::gentoo [3.7.0:0/3.7.0::gentoo] USE="caps dbus libvirtd macvtap nfs nls policykit qemu udev vepa -apparmor -audit -firewalld -fuse -glusterfs -iscsi -libssh -lvm -lxc -numa (-openvz) -parted -pcap -phyp -rbd -sasl (-selinux) -uml -virt-network -virtualbox -wireshark-plugins -xen -zeroconf -zfs" 14651 KiB [ebuild N ] net-libs/rpcsvc-proto-1.3.1::gentoo 58 KiB [blocks B ] <sys-libs/glibc-2.26 ("<sys-libs/glibc-2.26" is blocking net-libs/rpcsvc-proto-1.3.1) Total: 2 packages (1 upgrade, 1 new), Size of downloads: 14709 KiB Conflict: 1 block (1 unsatisfied) * Error: The above package list contains packages which cannot be * installed at the same time on the same system.

(In reply to Martin Mokrejš from comment #0) > I want to stay with glibc-2.25-r10 Then locally package.mask >=net-libs/rpcsvc-proto-1, since net-libs/rpcsvc-proto-0 is for <sys-libs/glibc-2.26.
Why is this INVALID? Couldn't the ebuild be improved to depend on net-libs/rpcsvc-proto-0 if user has <glibc-2.26 ?
Such type of dependency is impossible. Dependencies can be conditional only on USE flags, not on versions of other packages.
That is bad. Could emerge be improved to allow such dependencies? Why emerge does not pick automatically net-libs/rpcsvc-proto-0 if >net-libs/rpcsvc-proto-0 are blocking? Why does it blindly go for the highest unmasked version?It should go the highest while compatible version instead.
