Then I get:

It requires wxcore ==0.12.1.7 For the dependency on wxcore ==0.12.1.7 there are these packages: wxcore-0.12.1.7. However none of them are available. wxcore-0.12.1.7 was excluded because of the top level dependency wxcore ==0.13.1
I have hardcoded the wxcore==0.12.1.7 constraint in the reactive-banana-wx package because I didn't take the time to fix my installation problems with the newer wx package yet. You can override this by downloading the tarball from hackage and changing the dependency in reactive-banana-wx.cabal from build-depends: wxcore == 0.12.2.7 to the version you desire. Same for the wx == .. constraint. Then, simply type cabal install to install from the *.cabal file in your current directory. Best regards, Heinrich Apfelmus -- http://apfelmus.nfshost.com
