Created attachment 411084 [details, diff] eutils.eclass.patch Although epatch_user should be deprecated by proper PM functions, it is still discriminating non-portage users by forcing them to use portage specific locations in epatch_user. This could be transitionally fixed with the attached patch. https://github.com/gentoo/gentoo/pull/69
I will apply this in two weeks.
looks fine
