Hi, I'm new to haskell and wonted to start tinkering a bit with this language, specifically with HXQ. I have installed ghc with macports. Now while building HXQ I get the following error: Main.hs:20:9: Not in scope: type constructor or class `C.SomeException' Unfortunately I'm also new to Mac OS X. Before I developed on Linux. It would be great, if someone could give me a hint. Thanks, Tobias PS: Below the details -- ~$ cabal install hxq Resolving dependencies... 'HXQ-0.11.0' is cached. Configuring HXQ-0.11.0...
