ghc782 - terminfo #2969
Description
installing ghc782 (nix-env -iA nixpkgs.ghc.ghc782) seems to install the terminfo package (there is a ~/.nix-profile/lib/ghc-7.8.2/terminfo-0.4.0.0 folder) but it's not picked up by cabal list --installed or ghc-pkg list.
For instance, trying to install terminfo either through cabal or nix causes an error:

The ghc bug for this is https://ghc.haskell.org/trac/ghc/ticket/8919 . Appears to be fixed, so might be solved in ghc 7.8.3 ...
