Hey Đorđe,

Do you use stack? If so, make sure that the project you are working on really uses `GHC 7.8.4`. 

P. S. Just shot in the air :-P

Greetings dear Haskell community,

I'm trying to use Spacemacs for Haskell development

but as soon as I open a .hs file ghc-mod dumps errors:

ghc-mod: <command line>: cannot satisfy -package-id base-4.6.0.1-8aa5d403c45ea59dcd2c39f123e27d57

I have ghc-mod version: 5.5.0.0 compiled by GHC 7.8.4.

GHC version : 7.8.4

Emacs: 24.5.1

Spacemacs: 0.105.18

OS: Ubuntu 14.04.4 LTS

Any help is appreciated,

Djordje Grbic
