I use entropy for most of my packages, and portage only when I need a package not in entropy or with different use flags.
I work with Python 3.3 a lot, and have found it necessary to add a lot of packages to /etc/portage/package.use/... with the python_targets_python3_3 flag. e.g. pip, scipy, etc.
says to never edit /etc/make.conf.
Is there a safe way to set python_targets_python3_3 as a global USE flag for portage that will not affect entropy?
Thanks in advance.
