nix build fails on apple silicon

On an M1 macbook running 14.4.1 using nix (Nix) 2.18.2.

At commit a68a1e7ed060ee5af2d638585d19e3510ddbf16c , nix build . fails to build. The previous commit (the flash attention commit) 9c67c2773d4b706cf71d70ecf4aa180b62501960 builds fine.

The error from nix log which seems pertinent follows:
