Issue 36: compile failure due to missing instance http://code.google.com/p/xmonad/issues/detail?id=36 New issue report by mvanier42: What steps will reproduce the problem? 1. runhaskell Setup.hs build 2. 3. What is the expected output? What do you see instead? I expect the program to compile. Instead I get this: XMonad.hs:62:5: No instance for (Read Rectangle) arising from the 'deriving' clause of a data type declaration at XMonad.hs:62:5 Possible fix: add an instance declaration for (Read Rectangle) When deriving the instance for `Read ScreenDetail' What version of the product are you using? On what operating system? Darcs head xmonad on Debian Linux unstable, with ghc-6.6.1 compiled from scratch. Please provide any additional information below. xmonad-0.2 compiles and runs fine on my machine. If this error is due to a module from XMonadContrib, please tag this issue with 'Component-Contrib' below.
