Calculating dependencies... done!

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:


  (dev-libs/boost-1.63.0:0/1.63.0::gentoo, ebuild scheduled for merge) pulled in by
    (no parents that aren't satisfied by other packages in this slot)

  (dev-libs/boost-1.62.0-r1:0/1.62.0::gentoo, installed) pulled in by
    >=dev-libs/boost-1.51.0:0/1.62.0= required by (dev-libs/liborcus-0.11.2:0/0.11::gentoo, installed)
    (and 8 more with the same problem)

NOTE: Use the '--verbose-conflicts' option to display parents omitted above

It may be possible to solve this problem by using package.mask to
prevent one of those packages from being selected. However, it is also
possible that conflicting dependencies exist such that they are
impossible to satisfy simultaneously.  If such a conflict exists in
the dependencies of two different packages, then those packages can
not be installed simultaneously. You may want to try a larger value of
the --backtrack option, such as --backtrack=30, in order to see if
that will solve this conflict automatically.

For more information, see MASKED PACKAGES section in the emerge man
page or refer to the Gentoo Handbook.

The following packages are causing rebuilds:

  (dev-libs/boost-1.63.0:0/1.63.0::gentoo, ebuild scheduled for merge) causes rebuilds for:
    (media-gfx/blender-2.78a-r1:0/0::gentoo, ebuild scheduled for merge)
    (media-libs/openimageio-1.6.13:0/0::gentoo, ebuild scheduled for merge)

Try adding liborcus too - IIRC portage doesn't consider all rebuilds outside of @world.
Comment 2 Adrian 2017-02-06 07:55:43 UTC
I used to have to switch between boost versions frequently while adding support for openshadinglanguage, and encountered this issue every time I needed to downgrade or upgrade boost.

You can get a more complete list of the packages which are conflicting if you run
# emerge -uDN --verbose-conflicts blender

As a workaround I couldn't find a better way than uninstalling boost, boost-build, blender and all of the conflicting packages (making a list as you do so) and reinstalling them.

So I would try to uninstall the 8 or so packages listed by
# emerge -uDN --verbose-conflicts blender
# emerge --unmerge blender boost boost-build liborcus ...
(I didn't use emerge -pvc blender boost boost-build liborcus ... as it reduces the number of packages you need to remove and later recompile, none of the conflicting packages on my system were critical)

Then try to reinstall just boost, boost-build and blender
# emerge -1av --verbose-conflicts boost boost-build blender
Continue to uninstall further conflicting packages until this succeeds

Lastly reinstall the remaining conflicting packages
# emerge -1v liborcus ...
and add blender back to the world set
# emerge --noreplace blender

Comment 4 Zac Medico gentoo-dev 2017-02-12 04:39:44 UTC
This is similar to bug 607244 in the sense that "partial" updates are error-prone, as described in bug 607244, comment #8.
