This is also reproducible on 20.03, commit f8248ab since @dsanson was having trouble building our project that uses that as its pinned nixpkgs ;-)

I don't know why diagrams-lib would need fsnotify. I don't think there's any way to make fsnotify work properly in ghcjs.

nixpkgs/pkgs/development/haskell-modules/configuration-nix.nix

Line 481 in 4e8f320

hinotify = if pkgs.stdenv.isDarwin then self.hfsevents else super.hinotify;

probably should be hinotify = if pkgs.stdenv.hostPlatform.isDarwin then self.hfsevents else super.hinotify;

Also: you might want https://github.com/ghcjs/diagrams-ghcjs instead.

No activity on this in a few years, I'll go ahead and close. If anyone is still stuck on this, feel free to send a PR to haskell-updates unbreaking this package.
