cabal install fails: <command line>: unknown package: (unknown)

[dirkz]

I've download ghc from here: https://github.com/ghcformacosx/ghc-dot-app/releases/download/v7.10.1-r0/ghc-7.10.1-r0.zip

$ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.10.1

OS X Yosemite 10.10.3

Steps to reproduce (in my situation):

$ rm -fr ~/.cabal/ ~/.ghc
$ cabal update
$ cd game-in-haskell
$ cabal sandbox init
$ cabal install --only-dependencies
<command line>: unknown package: (unknown)

Unfortunately, I don't see more specifics. -v doesn't seem to give more info:

$ cabal install -v --only-dependencies

Which setup are you using? Do you spot a mistake in my setup?

As a workaround, I was able to use ghc 7.8.4, globally install the needed packages (elerea, GLFW-b etc.) via stackage, and then build manually with ghc --make .... So there should be a possible solution to adapt the game-in-haskell-book.cabal to the packages in stackage LTS and it should work in a sandbox. Might try it.
