The cross-platform dissemination tracker (also known as the Gentoo "world domination" tracker) is for issues involving dissemination of Gentoo to alternative platforms such as Ubuntu, Windows, and Mac OS. This dissemination can ride on the success of the python language, which allows portage to be installed in a python venv on any OS. When installed in a venv, portage is automatically configured for prefix mode, with EPREFIX equal to the venv prefix itself, since portage-3.0.21: https://gitweb.gentoo.org/proj/portage.git/commit/?id=99d116d5b8d243aa4ed5365cbde05fa9e90bf6eb Simply create an venv, enter it with your shell (powershell on windows), and python -m pip install portage. Use `portageq envvar EPREFIX` to test the (automatic) venv EPREFIX configuration.
