with-packages-wrapper.nix
has a hack to workaround the linker limit in MacOS Sierra. However that is now broken with GHC 8.8, because of slight change in the format of the package config.

While in GHC 8.8, the entry is formatted as:
This PR fixes the linker hack by modifying the
grep
andsed
commands to pattern match on either space or new line, so that the hack can work on all versions of GHC.Things done
