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

dev-libs/glib:2

  (dev-libs/glib-2.36.4-r1::gentoo, installed) pulled in by
    (no parents that aren't satisfied by other packages in this slot)

  (dev-libs/glib-2.40.0-r1::gentoo, ebuild scheduled for merge) pulled in by
    >=dev-libs/glib-2.40:2 required by (dev-libs/gobject-introspection-1.40.0-r1::gentoo, ebuild scheduled for merge)
    (and 1 more with the same problem)


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.

page or refer to the Gentoo Handbook.
