Local copy of remote index is up-to-date and will be used.

These are the packages that would be merged, in order:

Calculating dependencies  . ...... .. ...... .. ....... .... done!
Dependency resolution took 106.69 s (backtrack: 9/20).


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

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.

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-qt/qtbase-6.7.3-r2-1:6/6.7.3::gentoo, binary scheduled for merge) causes rebuilds for:

The following USE changes are necessary to proceed:
 (see "package.use" in the portage(5) man page for more details)
# 
=dev-qt/qtdeclarative-6.7.2 -opengl -vulkan

 * In order to avoid wasting time, backtracking has terminated early
 * due to the above autounmask change(s). The --autounmask-backtrack=y
 * option can be used to force further backtracking, but there is no
 * guarantee that it will produce a solution.
