In simple terms, you have a conflict between something new and something
old, and portage can't do it.

In this case, portage wants to update numpy from to 1.9.0-r1, but can't.
The reason is the matplotlib ebuild requires a version of numpy <1.9.0
(ignore for now the python_targets stuff, that's USE-like requirements
which are not relevant).

Bottom line: with that version of matplotlib, you are pegged to the
current version of numpy, and portage is being overly complicated about
telling you this.

If you can't update matplotlib, you can just leave things as they are -
it doesn't hurt. Train your eye to ignore that output about numpy.
