Stack setup fails with package installation errors

I'm trying to get stack running for the first time, but running stack setup in an example project (from stack new helloworld new-template) fails with the following output (I skipped the beginning, which I think was normal):

Installing library in
/home/ajl/.stack/programs/x86_64-linux/ghc-7.10.2/lib/ghc7.10.2/ghc_JzwEp1oQ8kA7NFNTGk1ho5 "/home/ajl/.stack/programs/x86_64-linux/ghc-7.10.2/lib/ghc-7.10.2/bin/ghc-pkg" --force --global-package-db "/home/ajl/.stack/programs/x86_64-linux/ghc-7.10.2/lib/ghc-7.10.2/package.conf.d" update rts/dist/package.conf.install
Reading package info from "rts/dist/package.conf.install" ... done.

: Warning: Unrecognized field 420 on line 420
(Skipped unrecognized field for every line 419 down to 1)
: Warning: Unrecognized field 1 on line 1
: missing id field

: invalid package key:
make[1]: *** [install_packages] Error 1
make: *** [install] Error 2

Installing GHC ...%

I'm on Ubuntu 14.04, running stack 1.0.2. Not sure if it's relevant but I have ghc 7.10.1 with Cabal 1.23.0.0 installed on the system already, which work fine.

I have tried changing the resolver to older LTS versions with older ghc versions. I also tried deleting ~/.stack. Not sure what else to try given the unhelpfulness of the errors.

I figured it out. The GHC build uses grep to make packages.conf.install. I have GREP_OPTIONS=--color=auto -n set in my zsh config. The -n was putting line numbers in front of everything, which was causing the errors.

The reason I couldn't find packages.conf.install anywhere before is because it is made on the fly during GHC make. And stack does that in /tmp.
