Hi list, I’m very Haskell newbie, and I’m trying to install wxHaskell in order to try out reactive-banana-wx. What I did so far: 1 ) Installed lastest Haskell platform 2) Installed wxWidgets from source, latest dev version from http://sourceforge.net/projects/wxwindows/files/2.9.3/wxWidgets-2.9.3.tar.bz... compiled with ../configure --with-osx_cocoa 3 ) darcs get http://darcsden.com/kowey/wxhaskell-osx64-dave built this one But then doing 'cabal install reactive-banana-wx’ will start installing wxcore-0.12.1.7 when the step 3) already installed wxcore-0.13.1 and that is the repository that should have the wxHaskell which works in osx lion. So is it possible to tell reactive-banana-wx to use wxcore-0.13.1 instead of wxcore-0.12.1.7 ? best, Miguel Negrão
