From a876299acb15b84c9de61c28ac97379363dd5c97 Mon Sep 17 00:00:00 2001 From: Yifeng Li Date: Wed, 3 May 2023 23:45:59 +0000 Subject: [PATCH] dev-libs/libbsd: port to Darwin. This commit allows dev-libs/libbsd-0.9.1 to be built on Darwin (which is a dependency of many useful packages), thanks to the patch from NixOS.
