Fails to build on Mac

[unclechu]

Latest master doesn’t build on Mac: 1127770

This error pops up in the logs:

Undefined symbols for architecture x86_64:

I also see that the CI didn’t succeed for Macs for the latest commits:

It times out after around 6 hours (5h 59m 14s).

Used gRPC-haskell as an overlay (took overlay attribute). nixpkgs pin:
