Thanks for your answer. hspec is installed actually:
$ cabal install --only-dependencies
Resolving dependencies...
All the requested packages are already installed:
Use --reinstall if you want to reinstall anyway.
And yes, ‘spec’ is a typo, the error message appears as a tooltip in emacs so I cannot copy/paste it as text.
I still do have the error however….

I upgrade my emacs configuration with latest ghc-mod and all of sudden nothing works (again). When I try to load a .hs file from a project I got the first line highlighted with the error "cannot satisfy -package spec" and I cannot got type, info or doc from that file. Also I do not have anymore syntax errors highlighting I used to see.
As this message suggests, you need to install spec for testing.
% cabal install spec
# I don't know what the spec package is. A typo for hspec?
This is because ghc-mod obtains dependency for executables, libraries *and* testing.
In general, % cabal install --only-dependencies would help you.
