I also notice that if I use the git repo:head for wxHaskell on Linux, I get a similar error + Usage as windows, but on the command line. The version of wxHaskell that cabal fetches does not have this problem.
On windows, I took the repo:head because the released wxHaskell that cabal downloads had a compile failure for a ‘long long’ So perhaps there something that has changed in wxHaskell that causes a generic problem.
