0.6.2 already enjoyed a bump to EAPI-7 in commit 4ff644dd08166b9a00b23752e48b81a8c60888b1, but live ebuild was ignored ever since. 9999 ebuild contains a comment "# ebuild generated by hackport 0.5.1.9999". If you don't use this live ebuild in your workflow then please consider dropping it.
Thanks.
