[gentoo-user] "masked by: EAPI 7" trying up update "portage" - how to proceed

[n952162]

I haven't clue what to do here.  Can somebody supply a good URL or
explanation?

The emerge(1) man page says:

        EAPI   The EAPI variable in an ebuild(5) file is used to mask
packages that are not
               supported  by  the  current  version of portage. Packages
masked by EAPI can
               only be installed after portage has been upgraded.

but it's precisely portage that I'm trying to update.

The comand was:

     sudo emerge -vauU portage 2>&1 | tee -a portage.200611


01~>cat /tmp/portage.200611

  * IMPORTANT: 2 config files in '/etc/portage' need updating.

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

Calculating dependencies
  * IMPORTANT: 25 news items need reading for repository 'gentoo'.
  * Use eselect news read to view new items.

  * See the CONFIGURATION FILES and CONFIGURATION FILES UPDATE TOOLS
  * sections of the emerge man page to learn how to update config files.

newer version of portage before EAPI masked packages can be installed.
