As others have already commented, the notices in CAPITAL case above are not to 
be ignored.  Packages you installed require changing/updating their 
configuration files in /etc/, which portage won't do without your review and 
manual intervention.

There are a variety of tools to perform this configuration files update.  The 
notice provided by portage also tells you where to look:

So run 'man emerge' then type:

/CONFIGURATION\ FILES

and hit enter to search for "CONFIGURATION FILES" in the man page of the 
emerge command.

Additional information on the etc-update (installed by default) and other 
tools is given here:

When you ran '--autounmask-write' emerge saved some files specific to the 
license changes and perhaps other packages in /etc/ - it will not apply these 
automatically.  You have to merge or reject these yourself by using 'etc-
update'.  The interactive merge feature of 'etc-update' and other similar 
tools is quite useful when many changes need to be reviewed and applied on 
long configuration files.  Some of these changes you may want to apply, others 
reject, often within the same file.

Eventually you'll get the hang of this and go through the steps without much 
consternation.

HTH.
