You almost certainly want this to be:
emerge --update --verbose --oneshot portage
"--oneshot" will prevent portage from being added to your @world set.

Add "--oneshot", same reasoning as above.

delete the above line

add "--ignore" to ignore any cached files and fully examine the system.

Seeing so much "--resume" and "--skip-first" and "--keep-going"
frightens me.

Wow. This script makes me cry.

What have you set PYTHON_SINGLE_TARGET to? It *must* be one of:
* python2_7
* python3_4
