Looks like it's an issue with the cabal-macosx package, which will be fixed soon. You probably also want to install the examples, so try
cabal install -fbuildExamples
Not sure if I was suppose to try with that command, but If I do I get:

Errm, reactive-banana-0.6.0.0 is the current development branch which is definitely not going to compile. I meant the tarball from hackage, i.e. http://hackage.haskell.org/packages/archive/reactive-banana-wx/0.5.0.0/react...
I’m now trying to do a example where the value of a slider is posted to text box, but I can’t get it to work. event0 is for events that don’t ouput anything, but slider has a value.... what should I do ?
You can use fromPoll as the NetMonitor.hs examples demonstrates. Or you have to get an event from wx that indicates when the slider is moved, then you can use stepper or the fromChanges function. Best regards, Heinrich Apfelmus -- http://apfelmus.nfshost.com
