Situation: Binary package generator/server which is used to generate and provide binary packages to multiple binary package based PCs. Performed latest round of world updates on binary package host with no problems. On binary package using PCs, executed: emerge -gpuNDv --with-bdeps=y @world Received 3 warnings about USE flags: !!! The following binary packages have been ignored due to non matching USE: =media-gfx/iscan-2.26.2 use flag(s): png =dev-libs/popt-1.16-r1 use flag(s): static-libs =sys-fs/udev-164-r2 use flag(s): build NOTE: The --binpkg-respect-use=n option will prevent emerge from ignoring these binary packages if possible. Using --binpkg-respect-use=y will silence this warning Resolved the 'iscan' warning to remove a temporary line from /etc/portage/package.use on the binary package using PCs left over from a prior world update issue (i.e. bug in bugzilla now resolved). Resolved the 'popt' warning to a prior world update issue on the binary package host. Removed temporary line from /etc/portage/package.use and recompiled 'popt' package and made resulting binary available on host. Could not resolve 'udev' message. The 'udev' package was not selected for updating on the binary host server during it's last update world. On a binary package using PC, I executed the following with the associated results: slizard ~ # emerge -gpuNDv --with-bdeps=y --binpkg-respect=n @world > world.text 2>&1 slizard ~ # nano -w world.text slizard ~ # emerge -gpuNDv --with-bdeps=y @world > world2.text 2>&1 slizard ~ # diff world.text world2.text 75d74 < [binary U ] kde-base/kstartperf-4.7.2 [4.7.1] USE="(-aqua) -debug (-kdeenablefinal)" 77a77 > [binary U ] kde-base/kstartperf-4.7.2 [4.7.1] USE="(-aqua) -debug (-kdeenablefinal)" 209c209 < [binary U ] kde-base/kfourinline-4.7.2 [4.7.1] USE="handbook (-aqua) -debug (-kdeenablefinal)" --- > [binary U ] kde-base/knetwalk-4.7.2 [4.7.1] USE="handbook (-aqua) -debug (-kdeenablefinal)" 219c219 < [binary U ] kde-base/knetwalk-4.7.2 [4.7.1] USE="handbook (-aqua) -debug (-kdeenablefinal)" --- > [binary U ] kde-base/kfourinline-4.7.2 [4.7.1] USE="handbook (-aqua) -debug (-kdeenablefinal)" 324a325,333 > > !!!

No such line exists. Instead, the three packages 'kde-base/kstartperf-4.7.2', 'kde-base/kstartperf-4.7.2', 'kde-base/kfourinline-4.7.2' are listed as being different between the two sets of pretend emerge results. Yet visual inspection implies the lines are identical. What's weirder is that the message about 'udev' is for a previous version of udev. After the 'update world' on the binary host, 'eix udev' displays: [I] sys-fs/udev Available versions: 114 115-r1 119 124-r1 124-r2 141 (~)141-r1 146-r1!t 149 151-r4 164-r2{tbz2} (~)171-r1{tbz2} (~)171-r2{tbz2} **9999 {acl action_modeswitch build debug (+)devfs-compat edd (-)extras floppy gudev hwdb introspection keymap old-hd-rules +rule_generator selinux test} Installed versions: 171-r2{tbz2}(09:37:17 AM 09/14/2011)(acl extras gudev rule_generator -action_modeswitch -build -debug -edd -floppy -hwdb -introspection -keymap -selinux -test) Homepage: http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev.html Description: Linux dynamic and persistent device naming support (aka userspace devfs) BEFORE running 'update world' on a binary package using PC, 'eix udev' displays: [I] sys-fs/udev Available versions: 114 115-r1 119 124-r1 124-r2 141 (~)141-r1 146-r1!t 149 151-r4 164-r2{tbz2} (~)171-r1{tbz2} (~)171-r2{tbz2} **9999 {acl action_modeswitch build debug (+)devfs-compat edd (-)extras floppy gudev hwdb introspection keymap old-hd-rules +rule_generator selinux test} Installed versions: 171-r2{tbz2}(09:37:17 AM 09/14/2011)(acl extras gudev rule_generator -action_modeswitch -build -debug -edd -floppy -hwdb -introspection -keymap -selinux -test) Homepage: http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev.html Description: Linux dynamic and persistent device naming support (aka userspace devfs) i.e. Package 'udev' was not updated during this latest round of 'update' world on the binary host server and both the binary host server and the associated binary package using PCs are already running the same version of 'udev'.
Sorry - meant to put down 'sys-apps/portage-2.2.0_alpha60' in the one line desc. Not 'sys-apps/portage-2.2.0_alpha63'. 'alpha60' applies to the binary package using PCs prior to the new round of 'update world'. 'alpha63' applies to the binary package host after the new round of 'update world'. The ambiguous warning message comes from 'alpha60'. I don't know if 'alpha63' is subject to the same issue.
I can confirm the 'alpha63' version has the same issue. I updated portage on a binary package PC which had not yet gone through the 'update world' process. executing: emerge -gpuNDv --with-bdeps=y @world resulted with the same ambiguous/incorrect warning message.
We should only add binaries to ignored_binaries in _wrapped_select_pkg_highest_available_imp if we don't select select something with a higher version than the binary.
This is fixed in git: http://git.overlays.gentoo.org/gitweb/?p=proj/portage.git;a=commit;h=6622bb5b63b49b1e528d89fee061e40b2d0d5afd
This is fixed in 2.1.10.25 and 2.2.0_alpha65.
