virt-manager depends on libvirt, but the ebuild does not require or check that libvirt is installed with the "python" USE flag. When this happens virt-manager fails as shown: $ virt-manager Traceback (most recent call last): File "/usr/share/virt-manager/virt-manager.py", line 26, in <module> import libvirt ImportError: No module named libvirt The work-around is to ensure that libvirt is installed with the "python" USE flag.
