commit dee3dcf8d5a9b6b60e7adb29efa6e849e8538a52 Author: Aaron Bauman <bman@gentoo.org> Date: Sat Jun 2 15:41:06 2018 -0400 app-eselect/eselect-oodict: bump EAPI Package-Manager: Portage-2.3.40, Repoman-2.3.9
In EAPI=0, no src_prepare() is defined. If you handle files in WORKDIR directly in src_install, that is no problem. In EAPI=6 src_prepare() is defined and because S is not set, the entirely untested EAPI bump easily broke the ebuild.
