[gentoo-user] emerge world output seems a bit short on info

[Harry Putnam <reader@newsguy.com>]

Working on a new install of gentoo as vm (vbox) guest on win7.

Just checking if my partial install is out of date already with.  And
if a USE change was complicating things.

That change was to add -selinux.  I added that to make.conf after
seeing a selinux pkg flash by when I installed ... I think it was
'rsyslog'

Do I really need any selinux pkgs... I didn't mean to install it but
it got pulled in and I was a bit late in noticing.

I'd sooner have nothing to do with selinux.

I understand what the ouput is telling me, and how to arrange it, but
first I want to straighten out anything to do with selinux.

emerge -vuDp world... and get this confusing output:
