That sounds odd, and maybe wrong.
I believe I have gtk3 on my system.

home> dnf list gtk3*
gtk3.x86_64 3.20.9-1.fc24...

What error message do you get?
In general, proper new versions don't conflict with old versions.

Yes, I believe using something for one package
specific to a particular package isn't the right
way to go.

Why are you using stuff in /usr/local at all?
The package manager shouldn't put stuff there.

Still not clear on what you are up to, but you may want to adjust
the order things are retrieved with /usr/local closer to the front.
