Circular dependencies при установке sendmail

Вот такое получилось, когда решил поставить sendmail:

organisation admin # emerge -uav sendmail

 * IMPORTANT: 8 news items need reading for repository 'gentoo'.
 * Use eselect news to read news items.


These are the packages that would be merged, in order:

Calculating dependencies... done!

 * Use eselect news to read news items.
