When I try to install Phooey I get the following error: cabal install --constraint="Stream == 0.3" phooey Resolving dependencies... [1 of 1] Compiling Main ( /tmp/phooey-2.016943/phooey-2.0/Setup.lhs, /tmp/phooey-2.016943/phooey-2.0/dist/setup/Main.o ) Linking /tmp/phooey-2.016943/phooey-2.0/dist/setup/setup ... Configuring phooey-2.0... Warning: No 'build-type' specified. If you do not need a custom Setup.hs or ./configure script then use 'build-type: Simple'. Preprocessing library phooey-2.0... Building phooey-2.0... src/Graphics/UI/Phooey/WinEvents.hs:66:7: Could not find module `Data.Reactive': Use -v to see a list of the files searched for. It seems that the current version of reactive (0.10.5) no longer has Data.Reactive module (it seem to have been removed since 0.5 version of the reactive). Does Phooey really need 0.5 version of the reactive or is there a problem in my installation? Thanks Daryoush
