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).
