This is an ebuild for ccache-1.9 based on ccache-1.8. I have added a pkg_config function (it is only a quick hack but it seems to be working).
Created attachment 1718 [details] ccache-1.9 (update + pkg_config function)
should those symlinks be /usr/bin/gcc, etc?
I'll add a 1.9 to portage, based on my existing 1.8-r1. Note that pkg_config is deprecated.
