postgresql parallel builds fail on Darwin #51093
Description
Issue description
While trying to fix #50902 I was unable to build postgresql. The important lines from the build log (full log) seem to be:
ar crs libpgtypes.a numeric.o datetime.o common.o dt_common.o timestamp.o interval.o pgstrcasecmp.o
echo 'Libs: -L/nix/store/7l8df1na81psj9cx56yjs4m9084nrayr-postgresql-9.6.10-lib/lib -lecpg_compat' >>libecpg_compat.pc
error: /nix/store/p1zg3dnaaglqm34pq12ynfa2pc3r2lq8-cctools-port-895/bin/ranlib: can't open file: libpgtypes.a (No such file or directory)
ar: internal ranlib command failed
make[5]: *** [../../../../src/Makefile.shlib:306: libpgtypes.a] Error 1
The build succeeds with nix-build --cores 1 --max-jobs 1 -E 'let nixpkgs = import (builtins.fetchTarball { url = "https://github.com/endgame/nixpkgs/archive/bc565bba2762edf12a40fb0c153d676e66e28faa.tar.gz"; sha256 = "1hdcg4b84c0mw959d6x9pxal95j58ks82fpfsy5sbazs6s40hdhy"; }) {}; in nixpkgs.haskellPackages.postgresql-libpq'
Steps to reproduce
This build may fail:
nix-build -E 'let nixpkgs = import (builtins.fetchTarball { url = "https://github.com/endgame/nixpkgs/archive/bc565bba2762edf12a40fb0c153d676e66e28faa.tar.gz"; sha256 = "1hdcg4b84c0mw959d6x9pxal95j58ks82fpfsy5sbazs6s40hdhy"; }) {}; in nixpkgs.haskellPackages.postgresql-libpq'
(While it points to a commit in my fork of nixpkgs, this fork does not change the postgresql package. It updates something that depends on postgresql which I still haven't got building on Darwin.)
