The thing is that ghc-pkg check returns nothing.
Okay, I think that's a good sign, sort of. Does $ ghc-pkg list Cabal list one Cabal-1.8.0.6 in the global db and one in the user-db? If so, unregister the one in the user-db $ ghc-pkg unregister --user Cabal-1.8.0.6 If it complains that would break anything, post the message.

Hi beginners.
I'm getting an odd problem quite a lot recently:
ghc -fglasgow-exts --make -O2 -W X.hs -v -o X
package Cabal-1.8.0.6-ec9be469687b5a514f4b7e8e2b8343c7 is shadowed by package Cabal-1.8.0.6-c995b90190c27e1dfa2ab3d5434fabef
You have two versions of Cabal-1.8.0.6, probably you should unregister the one in the user-db.
