I'm in start of standard periodical world rebuild. For now is simple upgrade. I have autounmask on to save time with keywords, and use flag editing. I got problem with some python packages. Just one example: # required by dev-python/cffi-1.14.0-r3::gentoo # required by virtual/python-cffi-1::gentoo[-python_targets_python3_8,python_targets_python3_7,python_targets_python3_6] # required by dev-python/pycryptodome-3.9.8-r1::gentoo # required by net-im/gajim-1.2.1::gentoo[python_single_target_python3_7,crypt] # required by @selected # required by @world (argument) # /etc/portage/package.mask/custom.cldx: #virtual/blas::gentoo #virtual/cblas::gentoo #virtual/lapack::gentoo #sci-libs/lapack-reference::gentoo #sci-libs/gsl::gentoo #sci-libs/blas-reference::gentoo #sci-libs/cblas-reference::gentoo #app-admin/eselect #dev-java/icedtea-bin:7 #=media-libs/opencolorio-1.0.9-r4 =dev-python/pycparser-2.20-r2 As you look into ebuilds, dev-python/cffi-1.14.0-r3 doesn't specify minimal version for pycparser, yet it has no python3 support (so no reason to want pycparser-2.20-r2 from overlay). I'm certain that comment itself doesn't lie, because dev-python/cffi is only installed pycparser dependent. Reproducible: Always It happened earlier, though I don't see anything about it among my reports.

I was wrong about exact reason, it's indeed wrong comment. I did not notice =dev-python/cffi-1.14.3 below.

More exact case, now with linux-headers. Installed version 5.4-r1, version 5.10 is masked (same as for toolchain, to prevent unexpected toolchain upgrades). From upgrades still to be done, only pax-utils requires higher version than current (linux-headers-5.8), others are satisfied by version. But report reasoning from autounmask still has misleading requesters: The following mask changes are necessary to proceed: (see "package.unmask" in the portage(5) man page for more details) # required by virtual/os-headers-0-r2::gentoo # required by media-libs/zvbi-0.2.35-r1::gentoo # required by media-video/ffmpeg-4.3.2::gentoo[zvbi] # required by media-libs/aubio-0.4.9::gentoo[ffmpeg] # required by media-sound/ardour-6.6-r1::gentoo # required by @selected # required by @world (argument) # /etc/portage/package.mask/00_toolchain: =sys-kernel/linux-headers-5.10 virtual/os-headers only specified zero slot for headers.
There's even more ridiculous error case: # emerge -tav1 gimp These are the packages that would be merged, in reverse order: Calculating dependencies... done! Dependency resolution took 7.59 s.
