That message is normal on Gentoo after an emerge with autounmask.

Before continuing, update the Portage configuration files.

Check which files need attention:

sudo etc-update

or the newer interactive tool:

sudo dispatch-conf

For most systems, etc-update is simpler:

sudo etc-update

You will see something like:

1) /etc/portage/package.use
2) /etc/portage/package.accept_keywords
3) /etc/portage/make.conf
...

Choose:

-3

to review differences, then:

to replace with the new version, or

to keep your current version.

If these changes were created by Portage autounmask and you have not manually customized those files heavily, accepting the new versions is usually appropriate.
