[Haskell-beginners] getting cabal to work under windows 8

[Nathan Hüsken]

Hey,

I have installed haskell-plarform 2013.2.0.0 on windows 8.
I have MinGW + Msys isntalled.

I am trying to install some package with cabal. So I do:

cabal install netwire

in the msys console. Now I get:

cabal.exe: The program ghc-pkg is required but the version of c:\Program 
Files
(x86)\Haskell Platform\2013.2.0.0\bin\ghc-pkg.exe could not be determined.

ghc-pkg.exe exists at the given position. What am I missing?

Thanks!
Nathan
