Created attachment 288379 [details, diff] ebuild patch to modify ccache-config for prefix The current version of ccache-config adds a line that is not prefix ready. I've attached a working fix for current prefix ebuilds. However a better fix would also involve upstream. The current ccache-config sources /etc/init.d/functions.sh and then uses ${ROOT%/}. It would be nice to s/ROOT/EROOT/ but unfortunately the script doesn't always use ROOT where it ought to. It still references the /usr/ directly in one place. Thus upstream would have to fix that before prefix could replace ROOT.
Thanks. Tip: "diff -u <old> <new>" - You did the reverse.
