[Nix-dev] Haskell packages in the binary cache broken?

[Karn Kallio]

Looking at the end of your stage-4 log we see that a build failed because 
containers-0.4.2.1-75f143aa39a3e77a1ce2300025bdd8ce is missing.  That is part 
of ghc, and the nix hash of your ghc-wrapper is 
vlx3ikjjxlfvqjjlx74cg07p79y43mdq, which agrees with the Hydra trunk: 
http://hydra.nixos.org/build/4491149

So your ghc and the binary cache one should be the same, thus the missing 
containers should be there.

Would you check with

ghc-pkg -v --global list

whether or not your local GHC has the same containers as Hydra? From the build 
log errors I think it must not.

The Hydra ghc does have a containers with the right GHC ABI hash:
