these expressions are generated automatically from the Cabal file, which
means that patching them directly is not ideal, because the changes are
likely to be overwritten in the next update. I have modified cabal2nix
so that it generates a dependency on 'libc' for those packages, and that
attribute is then overridden in haskell-packages.nix. The effect should
be the same.

Take care,
Peter
