I did a package check, and I always get a ton of these things: Warning: haddock-html: E:\Plang\Haskell Platform\lib\extralibs\doc\haskell-src-1.0.1.4\html doesn't exist or isn't a directory Which I think is just missing documentation, so I ignore them. But this time I also got this: The following packages are broken, either because they have a problem listed above, or because they depend on a broken package. HTTP-4000.2.3 haskell-platform-2012.2.0.0 ghc-pkg list shows: Cabal-1.10.1.0 Cabal-1.10.2.0 Cabal-1.14.0 Cabal-1.14.0 GLUT-2.1.2.1 GLUT-2.1.2.1 GLUT-2.1.2.1 {HTTP-4000.2.3} HTTP-4000.2.5 ... {haskell-platform-2012.2.0.0} haskell-platform-2012.4.0.0 haskell-src-1.0.1.4 haskell-src-1.0.1.4 haskell-src-1.0.1.5 haskell-src-1.0.1.5 (haskell2010-1.0.0.0) (haskell2010-1.1.0.1) (haskell2010-1.1.0.1) haskell98-1.1.0.1 (haskell98-2.0.0.1) (haskell98-2.0.0.1) Not sure what it all means, but looks somewhat goofy to me. I always just do "cabal installs", and an occasional "-force-reinstalls" when told that it is the only option, but recently when they might fail tried a "cabal-dev install" a few times, I assume that is what the "{}" entries are, but am not sure if they can all peacefully coexist. Do I need to do a reset and start over? I hope not, as it took me many hours of fiddling to install some packages like glut, wxcore, and a few others. Argh. -------------------------------------------
