Initially gcc-toolchain was also in adhoc list. Now I have installed it as well. Here are the steps I took
Haskell Steps (doesn't work) 0.

Create .cabal file using "cabal init" [guix] user@machine:~/programs/haskell/test$ cabal init 6. Update cabal [guix] user@machine:~/programs/haskell/test$ cabal update 7.
