[Haskell-cafe] module is a package module error

[Martin Hilbig]

meh, i got confused with my different tests and not using cabal clean.

add this paragraph to your hint-test.cabal:

library
  hs-source-dirs:      src
  default-language:    Haskell2010
  Exposed-Modules:     Internal

remove 'import Internal' (or not)
remove 'loadModules ["Internal"]'
enjoy.

i think the error meant to say, this module source file you are trying
to load is already part of a package, which would be bad if loaded twice.

and since it's part of your package, you dont need to load it, just
import it.
