When trying to update my system, a block occurs: sys-apps/hal-0.5.12_rc1-r4 and kde-base/systemsettings-4.2.3 need virtual/libusb:0, whereas media-libs/libgphoto2-2.4.5 and sys-apps/usbutils-0.82 need virtual/libusb:1 Reproducible: Always Steps to Reproduce: 1. emerge -up --deep @world @system 2. 3. Actual Results: !!! Multiple package instances within a single package slot have been pulled !!! into the dependency graph, resulting in a slot conflict: virtual/libusb:0 ('ebuild', '/', 'virtual/libusb-0', 'merge') pulled in by =virtual/libusb-0* required by ('installed', '/', 'kde-base/systemsettings-4.2.3', 'nomerge') =virtual/libusb-0* required by ('installed', '/', 'sys-apps/hal-0.5.12_rc1-r4', 'nomerge')
