Please add to the ccache instructions, concerning the variables in /etc/portage/make.conf:

There is no drawback for adding this for portage compilation, and it will increase the number of hits in the long run (when upgrading packages). Also, in my experience adding the variables

are a good idea (and even the latter, though apparently aggressive, never caused any troubles for me).

Nevertheless, one could mention that changing such options invalidates the previous cache content (the first at least partially) so that immediately after the change you will get less hits.
