I'm receiving an error from ghc-mod in my cabal sandbox: %./.cabal-sandbox/bin/ghc-mod list Dummy:0:0:Error:<command line>: cannot satisfy -package cairo (use -v for more information) The obvious potential problem is that cairo isn't installed. However, %cabal repl Preprocessing executable 'Notation' for Notation-0.1.0.0... GHCi, version 7.6.3: http://www.haskell.org/ghc/ :? for help ... Prelude Main> import Graphics.Rendering.Cairo Prelude Graphics.Rendering.Cairo Main> My cabal file includes: build-depends: base >=4.6 && <4.7, mtl >=2.1 && <2.2, containers >=0.4 && <0.5, cairo >= 0.12 && <= 0.13 I'm on OSX 10.9.1. I had to point cairo to gcc-4.9 instead of clang to make it compile. Where else can I look for the problem? -- Brian
