4.8 for now. I was going to google and noodle around this issue, but
since you brought it up....

Naive question: Can't I use /usr/local/portage/..... I guess not,
nor my second 'dumb' idea to set it up as user 'portage'
Ok so what is the overview how to install it (hopefully using
standard gentoo methods) So that I can just use it for amd64
codes to test on test machines? Also, what about standard libs and
custome libs -[1]?
Later on I want to compile with it on arm64 in a cross compile environment
for the arm64 target (Cortex A53). [2]
