Created attachment 427416 [details, diff] updated timezone-data makefile patch Found it to be a simple version bump save a patch needing updating. Patch is below and is a forward port of the 2015c patch. The db CONTENTS files match up save of course the /usr/share folder so nothing looks out of place.
this was added a month ago already ... https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=48e2162c293601b6bc55a7ceab07e7e6aa2d3c88
Wasn't showing up in gitweb when I first looked but it's there now. Sorry for the noise.
