Use `eselect kernel list` : it will show which /lib/modules it will go
to (as an example here's mine):

$ eselect kernel list
Available kernel symlink targets:
  [1]   linux-4.1.37-gentoo *
  [2]   linux-4.9.16-gentoo

If I merge a package with kernel modules, it will currently go to
lib/modules/4.1.37-gentoo, which is what my kernel symlink is set to.
You can use `eselect kernel set` to change this symlink. In my case,
using `eselect kernel set 2` will change it to 4.9.16. In your case,
list the installed kernels and set it to the new kernel and `emerge -a
@module-rebuild` and you'll be good to go.
