compress-man-pages.sh uses `find ... | while ...; do...` so this works on darwin vcunat says the following in https://github.com/NixOS/nixpkgs/commit/94d164dd7#r22030369 > Unfortunately, process substitution doesn't work during early darwin bootstrap. http://hydra.nixos.org/build/52433342 We've run into that before. > I think it should work to have `find ... | while ...; do...`

# Check whether RPATHs or wrapper scripts contain references to

# It might be better to have Nix scan build output for any occurrence

# of $TMPDIR (which would also be good for reproducibility), but at

|
# info or assertion messages that refer to $TMPDIR).
