This alone works fine for me, and I don't find the naming confusing. I'm sure the way you referenced would also work, though it ends up dumping the configuration for every package into a single file. cat /etc/portage/env/media-tv/mythtv CFLAGS="-march=amdfam10 -Os -pipe -frename-registers -fweb" CXXFLAGS="-march=amdfam10 -Os -pipe -frename-registers -fweb" I would recommend that instead of just putting flags for each package in a separate file that you instead create a per-package config and then symlink it from the package name. As in: ls -l /etc/portage/env/media-tv/mythtv lrwxrwxrwx 1 root root 13 Oct 5 2012 /etc/portage/env/media-tv/mythtv -> ../noparallel -- Rich
